app: add GimpBacktrace GimpBacktrace provides an interface for creating and traversing multi-threaded backtraces, as well as querying symbol information. While we already have some backtrace functionality, it relies on external tools for the most part, and as such is rather expensive, and is only meant for producing opaque backtraces. GimpBacktrace, on the other hand, is meant to be relatively cheap (we're going to use it for profiling,) and allow inspection of the backtrace data. In the future, it might make sense to replace some, or all, of the other backtrace functions with GimpBacktrace. GimpBacktrace currently only supports Linux. By default, it uses dladdr() to query symbol information, which is somewhat limited (in particular, it doesn't work for static functions.) When libunwind is installed, GimpBacktrace uses it to get more complete symbol information. libunwind is currently an optional dependency, but it might make sense to promote it to a mandatory, or opt-out, dependency, as it's lightweight and widely available. On other platforms, the GimpBacktrace interface can still be used, but it always returns NULL backtraces.

app, pdb, libgimp: use "#pragma once" instead of: #ifndef __FOO_H__ #define __FOO_H__ /* declarations */ #endif /* __FOO_H__ */ And some cleanups while I saw the headers. This is far from finished...

app, meson: disable GimpBacktrace on Linux without execinfo.h. If execinfo.h was not found, do not try to compile gimpbacktrace-linux.c because the backtrace() API is not optional there. Also I'm further improving the meson summary, regarding "Dashboard Backtraces". Rather than just yes/no to say if the traces are detailed, let's go for finer-grained state, saying if the traces are completely deactivated ("no", e.g. when execinfo.h is not found), or "rough" (when libunwind and libbacktrace are not found) or "partially detailed" (one of these is not found) and finally "detailed". Also add info on missing dependency between parentheses to help packagers find the proper dependencies to get to the "detailed" state.

# define GIMP_BACKTRACE_BACKEND_LINUX
app: more cleanup in GimpBacktrace Improve out-of-range check in gimp_backtrace_find_thread_by_id(). Remove unnecessary #include <exchndl.h> in gimpbacktrace-windows.c, and revert commit 644234e99d18f9608e44c9a6338c73f3e4872168 (the DrMingw detection happens at runtime). The Windows backend can work without DrMingw, it just can't find all the symbols, and doesn't provide source-location information.

#elif defined (G_OS_WIN32) && defined (ARCH_X86)
app: add Windows backend to GimpBacktrace The Windows backend produces full, multithreaded backtraces. When DrMingw is available, it also provides full symbol and (where available) source-location information. Otherwise, it provides symbol information for most of our libraries, but not for the GIMP binary itself.
