Since the macros were moved to EflMacros.cmake, there is no reason to
keep CommonHeaderChecks.cmake anymore, put them all in
config/common.cmake
Keep the checks sorted so they're easy to organize.
Add missing check for prctl() and iconv() (which we were checking
iconv.h, but the code used '#if HAVE_ICONV').
make FUNC_CHECK(), TYPE_CHECK() and HEADER_CHECK() more general and
they can be set to a scope, like "eina", then all symbols are prefixed
with that. The scope is created with CHECK_INIT(), and
EFL_HEADER_CHECKS_FINALIZE() will finish that.
This makes it possible for cmake/config/eina.cmake +
cmake/post/eina.cmake to add stuff to the generated file, better than
hand edit the template.
CHECK_APPEND_DEFINE(name val) is now the base to add symbols to the
generated file in the current scope.
Then convert cmake/config/eina.cmake to use that and match the
autotools values (were a bit off).
This exposed enabling valgrind was broken due incorrect pkg-config
usage with cmake (it's not obvious), it was using just the libraries,
while LDFLAGS are needed to get -L/usr/lib/valgrind. Then also convert
to CFLAGS provided by pkg-config and make that automatic for
PKG_CONFIG_REQUIRES and PKG_CONFIG_REQUIRES_PRIVATE.
Also, eina-mempool modules use valgrind and must use that now that's
propagating correctly.
This brings in the checks for all the headers and function that are
required in eina. With this commit only a few other checks are missing.
This is NOT tested on windows or mac os i can just verify that it runs
here on a arch linux system.
