Provides access to a MulticastLock.
As specified by the Android API, broadcast/multicast packets may be
filtered on some phones unless the application explicitly acquires
a "MulticastLock".
On iOS devices without a physical home button iOS
shows a home indicator instead. This is often in the
way of the UI or the game.
Added a project setting to disable hidden home indicator.
The default value is to hide the home indicator
The new 'split_libmodules=yes' option is useful to work around linker
command line size limitations when linking a huge number of objects.
We're currently over 64k chars when linking libmodules.a on Windows
with MinGW, which triggers issues as seen in #30892.
Even on Linux, we can also reach linker command line size limitations
by adding more custom modules.
We force this option to True for MinGW on Windows, which fixes#30892.
Additional changes to lib splitting:
- Fix linking of the split module libs with interdependent symbols,
hacking our way into LINKCOM and SHLINKCOM to set the `--start-group`
and `--end-group` flags.
- Fix Python 3 compatibility in `methods.split_lib()`.
- Drop seemingly obsolete condition for 'msys' on 'posix'.
- Drop the unnecessary 'split_drivers' as the drivers lib is no longer
too big since we moved all thirdparty builds to modules.

We no longer compile for armv7 and x86 in the official export templates,
as those architectures are no longer relevant for iOS.
If users really want to support armv7 (used on devices from before
September 2013, e.g. iPhone 5), they can still build their own templates
and toggle the option.
We might remove the option altogether in a later release to avoid the
confusion for users that might tick the checkbox without having compiled
their own templates.
Fixes#34135.
The option is needed when using the 'fastcomp' backend (default before
1.39.0), and must not be defined when using 'upstream' (new default).
So we define it conditionally to support both backends.
Follow-up to #30751.
This allows setting the `read_chunk_size` of the internal HTTPClient.
This is important to reduce the allocation overhead and number of file
writes when downloading large files, allowing for better download speed.
Third-party platforms (e.g. console ports) need to be able to
disable JIT support in the regex module too, so it can't be
hardcoded in the module SCsub. This is cleaner this way anyway.
Fixes#19316.
Upstream Emscripten changed this in 1.39.1+, so IDBFS is no longer
included by default and has to be linked manually.
The explicit linking doesn't seem to be problematic on earlier
versions (tested `1.38.47-upstream`).
Fixes#33724.
A change in upstream Emscripten 1.39.1+ made our buildsystem error
out where it was previously only issuing a warning:
```
[ 5%] Linking Static Library ==> main/libmain.javascript.opt.bc
shared:WARNING: Assuming object file output in the absence of `-c`, based on output filename. Please add with `-c` or `-r` to avoid this warning
Ranlib Library ==> main/libmain.javascript.opt.bc
/opt/emsdk/upstream/bin/llvm-ranlib: error: unable to load 'main/libmain.javascript.opt.bc': file too small to be an archive
```
As advised on emscripten-core/emscripten#9806, we should be using
`emar` here to create the static library and not `emcc`.
This was apparently done to workaround Emscripten issues in the past,
but evidently this is no longer necessary.
The rest of the `env` redefinitions should probably be re-assessed
against the current state of Emscripten.
Fixes#33374.
