85c841cb45 msvc: drop exception, make BIT() a bitfield with Visual Studio
Add casts to `bool`, or use `bit` type in local variables, where
neccessary to avoid MSVC compiler warnings C4242.

Note: There may remain places needing the above updates, where not
tested in CI, and missed in manual review.

Also:
- urldata: convert struct field `connect_only` to bitfield to match its
  counterpart in another struct.
- rename curl-specific `bit` type to `curl_bit`.

e8415a8296 lib: drop, or replace sendf.h with curl_trc.h where possible
- replace `sendf.h` with `curl_trc.h` where it was included just for it.
- drop unused `curl_trc.h` includes.
- easy: delete obsolete comment about `send.h` include reason.

Also:
- move out `curl_trc.h` include from `sendf.h` and include it directly
  in users, where not done already. To flatten the include tree and
  to less rely on indirect includes.
- stop including `sendf.h` from other headers, replace it with forward
  declaration of `Curl_easy`, as done already elsewhere.

193cb00ce9 build: stop overriding standard memory allocation functions
Before this patch curl used the C preprocessor to override standard
memory allocation symbols: malloc, calloc, strdup, realloc, free.
The goal of these is to replace them with curl's debug wrappers in
`CURLDEBUG` builds, another was to replace them with the wrappers
calling user-defined allocators in libcurl. This solution needed a bunch
of workarounds to avoid breaking external headers: it relied on include
order to do the overriding last. For "unity" builds it needed to reset
overrides before external includes. Also in test apps, which are always
built as single source files. It also needed the `(symbol)` trick
to avoid overrides in some places. This would still not fix cases where
the standard symbols were macros. It was also fragile and difficult
to figure out which was the actual function behind an alloc or free call
in a specific piece of code. This in turn caused bugs where the wrong
allocator was accidentally called.

To avoid these problems, this patch replaces this solution with
`curlx_`-prefixed allocator macros, and mapping them _once_ to either
the libcurl wrappers, the debug wrappers or the standard ones, matching
the rest of the code in libtests.

This concludes the long journey to avoid redefining standard functions
in the curl codebase.

Note: I did not update `packages/OS400/*.c` sources. They did not
`#include` `curl_setup.h`, `curl_memory.h` or `memdebug.h`, meaning
the overrides were never applied to them. This may or may not have been
correct. For now I suppressed the direct use of standard allocators
via a local `.checksrc`. Probably they (except for `curlcl.c`) should be
updated to include `curl_setup.h` and use the `curlx_` macros.

This patch changes mappings in two places:
- `lib/curl_threads.c` in libtests: Before this patch it mapped to
  libcurl allocators. After, it maps to standard allocators, like
  the rest of libtests code.
- `units`: before this patch it mapped to standard allocators. After, it
  maps to libcurl allocators.

Also:
- drop all position-dependent `curl_memory.h` and `memdebug.h` includes,
  and delete the now unnecessary headers.
- rename `Curl_tcsdup` macro to `curlx_tcsdup` and define like the other
  allocators.
- map `curlx_strdup()` to `_strdup()` on Windows (was: `strdup()`).
  To fix warnings silenced via `_CRT_NONSTDC_NO_DEPRECATE`.
- multibyte: map `curlx_convert_*()` to `_strdup()` on Windows
  (was: `strdup()`).
- src: do not reuse the `strdup` name for the local replacement.
- lib509: call `_strdup()` on Windows (was: `strdup()`).
- test1132: delete test obsoleted by this patch.
- CHECKSRC.md: update text for `SNPRINTF`.
- checksrc: ban standard allocator symbols.

70779199f3 cf: replace the method get_host with query
Connection filters had a method `get_host()` which had not really been
documented. Since then, the cf had the `query()` method added. Replace
the separate get_host with query.

Add `CF_QUERY_HOST_PORT` as query to connection filters to retrieve
which remote hostname and port the filter (or its sub-filter) is talking
to. The query is implemented by HTTP and SOCKS filters, all others pass
it through.

Add `Curl_conn_get_current_host()` to retrieve the remote host and port
for a connection. During connect, this will return the host the
connection is talking to right now. Before/After connect, this will
return `conn->host.name`.

This is used by SASL authentication.

255aac56f9 curlx: move into to curlx/
Move curlx_ functions into its own subdir.

The idea is to use the curlx_ prefix proper on these functions, and use
these same function names both in tool, lib and test suite source code.
Stop the previous special #define setup for curlx_ names.

The printf defines are now done for the library alone. Tests no longer
use the printf defines. The tool code sets its own defines. The printf
functions are not curlx, they are publicly available.

The strcase defines are not curlx_ functions and should not be used by
tool or server code.

dynbuf, warnless, base64, strparse, timeval, timediff are now proper
curlx functions.

When libcurl is built statically, the functions from the library can be
used as-is. The key is then that the functions must work as-is, without
having to be recompiled for use in tool/tests. This avoids symbol
collisions - when libcurl is built statically, we use those functions
directly when building the tool/tests. When libcurl is shared, we
build/link them separately for the tool/tests.

7b2d98dfad sasl: make login option string override http auth
- Use http authentication mechanisms as a default, not a preset.

Consider http authentication options which are mapped to SASL options as
a default (overriding the hardcoded default mask for the protocol) that
is ignored if a login option string is given.

Prior to this change, if some HTTP auth options were given, sasl mapped
http authentication options to sasl ones but merged them with the login
options.

That caused problems with the cli tool that sets the http login option
CURLAUTH_BEARER as a side-effect of --oauth2-bearer, because this flag
maps to more than one sasl mechanisms and the latter cannot be cleared
individually by the login options string.

New test 992 checks this.

3f8fc25720 cmake: add support for "unity" builds
Aka "jumbo" or "amalgamation" builds. It means to compile all sources
per target as a single C source. This is experimental.

You can enable it by passing `-DCMAKE_UNITY_BUILD=ON` to cmake.
It requires CMake 3.16 or newer.

It makes builds (much) faster, allows for better optimizations and tends
to promote less ambiguous code.

Also add a new AppVeyor CI job and convert an existing one to use
"unity" mode (one MSVC, one MinGW), and enable it for one macOS CI job.

Fix related issues:
- add missing include guard to `easy_lock.h`.
- rename static variables and functions (and a macro) with names reused
  across sources, or shadowed by local variables.
- add an `#undef` after use.
- add a missing `#undef` before use.
- move internal definitions from `ftp.h` to `ftp.c`.
- `curl_memory.h` fixes to make it work when included repeatedly.
- stop building/linking curlx bits twice for a static-mode curl tool.
  These caused doubly defined symbols in unity builds.
- silence missing extern declarations compiler warning for ` _CRT_glob`.
- fix extern declarations for `tool_freq` and `tool_isVistaOrGreater`.
- fix colliding static symbols in debug mode: `debugtime()` and
  `statename`.
- rename `ssl_backend_data` structure to unique names for each
  TLS-backend, along with the `ssl_connect_data` struct member
  referencing them. This required adding casts for each access.
- add workaround for missing `[P]UNICODE_STRING` types in certain Windows
  builds when compiling `lib/ldap.c`. To support "unity" builds, we had
  to enable `SCHANNEL_USE_BLACKLISTS` for Schannel (a Windows
  `schannel.h` option) _globally_. This caused an indirect inclusion of
  Windows `schannel.h` from `ldap.c` via `winldap.h` to have it enabled
  as well. This requires `[P]UNICODE_STRING` types, which is apperantly
  not defined automatically (as seen with both MSVS and mingw-w64).
  This patch includes `<subauth.h>` to fix it.

cace68e299 openldap: fix missing sasl symbols at build in specific configs
If curl is built with openldap support (USE_OPENLDAP=1) but does not
have also some other protocol (IMAP/SMTP/POP3) enabled that brings
in Curl_sasl_* functions, then the build will fail with undefined
references to various symbols:

ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_decode_mech'
ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_parse_url_auth_option'
ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_cleanup'
ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_can_authenticate'
ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_continue'
ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_start'
ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_init'

This was tracked down to these functions bein used in openldap.c but
defined in curl_sasl.c and then forward in two vauth/ files to have
a guard against a set of #define configurations that was now extended
to cover also this case.

Example configuration targeted that could reproduce the problem:

 - ssl_connect_data is remove from struct connectdata and made internal

 - ssl_connect_data is allocated in the added filter, kept at cf->ctx

 - added function to let a ssl filter access its ssl_primary_config and
   ssl_config_data this selects the propert subfields in conn and data,
   for filters added as plain or proxy
 - adjusted all backends to use the changed api
 - adjusted all backends to access config data via the exposed
   functions, no longer using conn or data directly

cfilter renames for clear purpose:

 - methods `Curl_conn_*(data, conn, sockindex)` work on the complete
   filter chain at `sockindex` and connection `conn`.
 - methods `Curl_cf_*(cf, ...)` work on a specific Curl_cfilter
   instance.
 - methods `Curl_conn_cf()` work on/with filter instances at a
   connection.
 - rebased and resolved some naming conflicts
 - hostname validation (und session lookup) on SECONDARY use the same
   name as on FIRST (again).

new debug macros and removing connectdata from function signatures where not
needed.
