e5b335d367 Don't use -ffast-math or other unsafe math optimizations
Godot supports many different compilers and for production releases we
have to support 3 currently: GCC8, Clang6, and MSVC2017. These compilers
all do slightly different things with -ffast-math and it is causing
issues now. See #24841, #24540, #10758, #10070. And probably other
complaints about physics differences between release and release_debug
builds.

I've done some performance comparisons on Linux x86_64. All tests are
ran 20 times.

Bunnymark: (higher is better)
(bunnies)    min    max  stdev average
fast-math   7332   7597    71     7432
this pr     7379   7779   108     7621 (102%)

FPBench (gdscript port http://fpbench.org/) (lower is better)
(ms)
fast-math  15441  16127   192    15764
this pr    15671  16855   326    16001  (99%)

Float_add (adding floats in a tight loop) (lower is better)
(sec)
fast-math   5.49   5.78  0.07     5.65
this pr     5.65   5.90  0.06     5.76  (98%)

Float_div (dividing floats in a tight loop) (lower is better)
(sec)
fast-math  11.70  12.36  0.18    11.99
this pr    11.92  12.32  0.12    12.12  (99%)

Float_mul (multiplying floats in a tight loop) (lower is better)
(sec)
fast-math  11.72  12.17  0.12    11.93
this pr    12.01  12.62  0.17    12.26  (97%)

I have also looked at FPS numbers for tps-demo, 3d platformer, 2d
platformer, and sponza and could not find any measurable difference.

I believe that given the issues and oft-reported (physics) glitches on
release builds I believe that the couple of percent of tight-loop
floating point performance regression is well worth it.

This fixes #24540 and fixes #24841

cf124b1415 Use XInput2 RawMotion to generate MouseMotion events
The current system for capturing the mouse and generating motion events on X11
has issues with inaccurate and lopsided input. This is because both
XQueryPointer and XWarpPointer work in terms of integer coordinates when the
underlying X11 input driver may be tracking the mouse using subpixel
coordinates. When warping the pointer, the fractional part of the pointer
position is discarded.

To work around this issue, the fix uses raw motion events from XInput 2. These
events report relative motion and are not affected by pointer warping.
Additionally, this means Godot is able to detect motion at a higher resolution
under X11. Because this is raw mouse input, it is not affected by the user's
pointer speed and acceleration settings. This is the same system as SDL2 uses
for its relative motion.

Multitouch input on X requires XInput 2.2. Raw motion events require
XInput 2.0. Since 2.0 is old enough, this is now the minimum requirement to
use Godot on X.

b526088ae2 X11: Link libgcc statically with use_static_cpp option
We were already linking libstdc++ statically for official binaries,
protecting us against most portability issues. But apparently since
we started using GCC 7 for official builds, we also need to link
libgcc statically for at least 32-bit builds to be portable.

Fixes #16409.

db49f35ab8 SCons: Fix usage of LD when we meant LINK
Also made LINK and CXXFLAGS configurable as command line options.
Note that LINK currently expects the *compiler* that will be used
for linking and will call its configured linker behind the scenes
(so g++, clang++, etc., not ld.gold). See #15364 for details.

9f134aa5d1 Cleanup old references to GLES2 renderer
There are still some left in the Android Java code, even stuff to swap between
GLES1 and GLES2 support from early Godot days... would be good to see some cleanup
there too one day.

The "graphics/api" option for Android exports is removed, as only GLES 3.0 is supported.
It can be readded when GLES 2.0 support comes back. Fixes #13004.

Travis always has massive backlog of macOS builds, so we can't rely on them

issues, so replacing it by an appropriate X11 build.

88be952fc9 Create separate debug info files by default
Now that we have a built-in stacktrace on a segfault it would be useful
to have debug information on debug_release builds so that bugreports can
include this information. Without this debug info we will still get
function names in the backtrace but not file location.

This commit will by default build all targets with minimal debug info
and then strip the information into separate files. On MacOS this is a
.dSYM file, on Linux/MingW this is a .debug file. MacOSX will
automatically load a dSYM file if it exists in its debugger. On
Linux/MingW we create a 'gnu debuglink' meaning that gdb and friends
will automatically find the debug symbols if they exist.

Existing workflow for developers does not change at all, except that we
now create two instead of one build artifact by default.

This commit also adds a 'debug_symbols' option to X11, MacOS, and MingW
targets. The default is 'yes' which corresponds to -g1. The alternatives
are 'no' (don't generate debug infos at all) or 'full' which runs with
-g2. A target=debug build will now build with -g3.

d44414c711 Disable -ffast-math for etc2comp
Apparently -ffast-math generates incorrect code with recent versions of
GCC and Clang. The manual page for GCC warns about this possibility.

In my tests it doesn't actually appear to be measurably slower in this
case, and this is used in a batch process so it seems safe to disable
this.

This fixes #10758 and fixes #10070

e3e2f06324 Replacement of internal RegEx with PCRE2
The pattern and replacement matching behaviour has been changed purely
due to the nature of switching to a standards-compliant library.

One mistake in the previous behaviour was that named groups didn't have
a number. This has been corrected.

As names are actually just an alias of numbered groups,
RegExMatch::get_name_dict() is now get_names() and is a dict
referring to the group number it represents.

Duplicate names are enabled and the with the first matching instance
used.

Due the lack of a suitable equivalent in PCRE2, RegExMatch::expand() was
removed.

e91a267a7c Buildsystem: Improve detect.py readability and fix issues
Tried to organize the configure(env) calls in sections, using the same order
for all platforms whenever possible.

Apart from cosmetic changes, the following issues were fixed:
- Android: cleanup linkage, remove GLESv1_CM and GLESv2
- iPhone: Remove obsolete "ios_gles22_override" option
- OSX:
  * Fix bits detection (default to 64) and remove obsolete "force_64_bits" option
    (closes #9449)
  * Make "fat" bits argument explicit
- Server: sync with X11
- Windows: clean up old DirectX 9 stuff
- X11:
  * Do not require system OpenSSL for building (closes #9443)
  * Fix typo'ed use_leak_sanitizer option
  * Fix .llvm suffix overriding custom extra_suffix
