fmin() is a function that is introduced with C99/C++11, so check for the
presence of it and provide a simple implementation for it if it does not
exist.
Also update the config.h.win32.in template accordingly, since this
function is provided on Visual Studio 2013 or later.
This was added with https://bugzilla.gnome.org/show_bug.cgi?id=148032
to make gtk compile against X11R5, see commit 3b9a31df0
That release is >20 years old now, so we can safely remove it.
The motivation for this is to remove any checks that we don't have in the
meson build.
httpGetAuthString() was added with cups 1.3 and we depend on a newer version
now. The direct field access was a fallback in case httpGetAuthString()
was missing, so this can also be dropped.
This is a backport of the GdkProfiler from master. It does not include
the pixel bandwidth numbers that come from gdkdrawcontext.c since there
does not seem to be an analog in 3.x.
Additionally, this implements the recent changes for SYsprof's D-Bus
profiler API which adds a Capabilities property and an options hash-table
to the D-Bus interface for forward portability.
Various adjustments to make the config.h output between autotools
and meson more similar by testing on Linux and Windows/MSYS2.
Setting things to 1 instead of true and shifting things around is motivated
by reducing the diff between the generated files.
This changes the configure option into two states:
auto: build all that can be build (default)
A list of backend names: build them and fail if we can't
"papi" is missing because it's not in Debian and I can't test it.
