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.

KNOWN ISSUES: - running tests with unity builds may fail in cases. - some build configurations/env may not compile in unity mode.
