Rémi Verschelde 5bc2cf257b Convert DOS line endings to Unix line endings 
Should fix issues some of us have with `misc/dist/uwp_template/AppxManifest.xml`
always showing up as modified.
Might cause issues on Windows due to the removal of BOMs or change of line endings
in some of the Mono, UWP or gradlew.bat files, we will test and adapt if need be.

Zher Huei Lee 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.

Ruslan Mustakov fbb27a0c43 Fix android export templates build 
This commit fixes errors occurring during Android export template

This required modification in third-party library (libpng) to compile
with NEON. Most likely a similar patch will be applied by them and we
could then replace the modified version.

Rémi Verschelde edbc0c0d0b freetype: Make it a module and split thirdparty library 
Comment out the weird workaround for building on Windows at it might
not be needed anymore. Testing needed to confirm.

Rémi Verschelde cbf52606f4 zlib: Split thirdparty files, simplify scons option 2016-10-15 12:20:47 +02:00
Rémi Verschelde 36738ddda4 glew: Split thirdparty files and isolate env 
Not fully happy about the way this one interacts with the various
platforms. Maybe the platform_config.h should be generated by the
SCsub instead of passing a define just to know where is the header.

Rémi Verschelde d9a291f641 ogg/vorbis/opus: Make them modules and unbundle thirdparty libs 
Took the opportunity to undo the Godot changed made to the
opus source. The opus module should eventually be built in its
own environment to avoid polluting others with too many include
dirs and defines.

TODO: Fix the platform/ stuff for opus.

Rémi Verschelde ee3cf211c6 webp: Make it a module and unbundle libwebp thirdparty files 
Note that there are two Godot-specific changes made to libwebp
for the javascript/HTML5 platform. They are documented in the
README.md.

Rémi Verschelde b1e8889d96 dds/etc1/pbm/pvr: Make those modules and split thirdparty files 
They are not particularly packaged in Linux distros so we do not
facilitate unbundling via SCons. There could be done if/when there
is interest.

Also s/pnm/pbm/, long-lived typo :)

Rémi Verschelde c31ad71f10 enet: Split enet thirdparty files and allow unbundling 
Building against shared libraries only implemented for Linux X11 so far.
TODO: Document Godot's modifications of upstream enet.

Rémi Verschelde 5fef84a135 png: Split library to thirdparty dir and allow unbundling 
Uses the new structure agreed upon in #6157, but the thirdparty/ folder
does not behave following a logic similar to that of modules/ yet.

The png driver can't be moved to a module as discussed in #6157, as it's
required by core together with a few other ImageLoader implementations
(see drivers/register_driver_types.cpp:register_core_driver_types())

Dropped the possibility to disable PNG support, it's a core component
of Godot.
