bzip2/lz4/lzma/lzo/snappy compression is now provided via *services*
they're almost like normal services, but in include/providers/
and they're supposed to provide exactly the same interface
as original compression libraries (but not everything,
only enough of if for the code to compile).
the services are implemented via dummy functions that return
corresponding error values (LZMA_PROG_ERROR, LZO_E_INTERNAL_ERROR, etc).
the actual compression libraries are linked into corresponding
provider plugins. Providers are daemon plugins that when loaded
replace service pointers to point to actual compression functions.
That is, run-time dependency on compression libraries is now on plugins,
and the server doesn't need any compression libraries to run, but
will automatically support the compression when a plugin is loaded.
InnoDB and Mroonga use compression plugins now. RocksDB doesn't,
because it comes with standalone utility binaries that cannot
load plugins.
SFORMAT() SQL function that uses fmtlib (https://fmt.dev/)
for python-like (also Rust, C++20, etc) string formatting
Only fmtlib 7.0.0+ is supported, older fmtlib
produces different results in the test.
No native support for temporal and decimal values,
* TIME_RESULT is handled as STRING_RESULT
* DECIMAL_RESULT as REAL_RESULT
This gives a short overview over found/missing dependencies as well
as enabled/disabled features.

* Report all plugins enabled via MYSQL_ADD_PLUGIN
* Simplify code. Eliminate duplication by making use of WITH_xxx
variable values to set feature "ON" / "OFF" state.

This is not enabled by default, as there are leaks in the
server that needs to be fixed first. One can compile
with -DUSE_MYSYS_NEW to find the memory leaks from
'new'. More comments can be found in mysys/my_new.cc
This is incosistent with other single config generators, where
the default type has always been RelWithDebInfo.
Fixed by moving setting of CMAKE_BUILD_TYPE right before PROJECT.
When CMAKE_CROSSCOMPILING_EMULATOR is defined, a cross-compile
can be made, however with native (emulated) execution possible.
This commit takes those points in the build system that
execute built targets natively and allow these to be executed
in a crosscompile if CMAKE_CROSSCOMPILING_EMULATOR is defined.
Closes#1805
