MSVC's /WHOLEARCHIVE and GCC/Clang's -Wl,--whole-archive options are
often sold as allowing the developer to reexport symbols coming from
static dependencies. However, this is not the complete picture.
While it is true in both ELF and MachO, which merge the symbol tables
into one [1], in PE this is not the case when the end binary is a DLL.
For this case, projects like FFmpeg extract the symbol table from the
static version and then construct a module definition file to mark
them as exported [2].
The approach in this platform is to, for the Windows and Cygwin cases,
reexport the libraries that are intended to be link_whole'd for
downstream consumption. Alternatively, the libraries in exposed_libs
need to be dumpbin'd individually and then a .def has to be constructed
for the whole [3].

Newer macOS provides /usr/lib/pkgconfig/libpcre2-8.pc which is broken
because it says headers are in /usr/include but that directory doesn't
exist. It can only be used to find the library, which only exists on
newer macOS at /usr/lib/libpcre2-8.dylib, so it's also unusable.
So, force usage of the subproject for glib.

In the case of a gstreamer-full target type to static,
the GST_STATIC_COMPILATION is necessary on Windows to avoid
a different mangling from the external project using the
gstreamer-full libraries (ie dllimport).
Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/4128>
Allow a project to use gstreamer-full as a static library
and link to create a binary without dependencies.
Introduce the option 'gst-full-target-type' to
select the build type, dynamic(default) or static.
In gstreamer-full/static build configuration gstreamer (gst.c)
needs the symbol gst_init_static_plugins which is defined
in gstreamer-full.
All the tests and examples are linking with gstreamer but the
symbol gst_init_static_plugins is only defined in the gstreamer-full
library. gstreamer-full can not be built first as it needs to know what plugins
will be built.
One option would be to build all the examples and tests after
gstreamer-full as the tools.
Disable tools build in subprojects too as it will be built at the end of
build process.

Starting with Meson 0.62, meson automatically populates the variables
list in the pkgconfig file if you reference builtin directories in the
pkgconfig file (whether via a custom pkgconfig variable or elsewhere).
We need this, because ${prefix}/libexec is a hard-coded value which is
incorrect on, for example, Debian.
Bump requirement to 0.62, and remove version compares that retained
support for older Meson versions.

First, just installing certifi doesn't install the ca-cert in the
right location. The `Install Certificates.command` script also
symlinks the openssl cert.pem to the certifi ca cert file
Second, we can make it more likely that users will notice this if we
make it a warning. If we ever get a bug report about this despite
these measures, we can try to make this an error.

The documentation within meson highlights, that `ninja` can be used
without problems for any case except `ninja reconfigure`. The warning
however describes to the user, that `ninja` shouldn't be used at all.
Fix the warning.
Fixes: 01eb252f67 Don't allow people to run meson inside the uninstalled env
Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1743>
Remove the symbolic link `gst-uninstalled` which points to `gst-env`.
The `uninstalled` is the old name and the project should stick to a
single name for the procedure.
Remove the term from all the files, exceptions are variables from
dependencies like `uninstalled_variables` from pkgconfig and
`meson-uninstalled`.
Adjust mentions of the script in the documentation and README.
