The added material comes from the Oxidation wiki's FAQ and the "Building
Firefox with Rust code" MDN page:
https://wiki.developer.mozilla.org/en-US/docs/Mozilla/Firefox/Building_Firefox_with_Rust_code
Once this commit lands, I will (a) remove the wiki FAQ entries, and (b) replace
the contents of that MDN page with a link to these build docs. There's no point
having overlapping docs, and in-tree is the best place for this information.
This commit also makes the capitalization of sub-headings more consistent.

When linking a weak symbol in an object against a library where the
symbol is provided with a version, the final binary get a weak versioned
symbol reference.
It turns out weak versioned symbols still make the dynamic linker need
the symbol version, even if all symbols needed with that version are
weak.
Practically speaking, that means with bug 1634204, we now end up with
a weak versioned symbol reference to __cxa_thread_atexit_impl with
version GLIBC_2.18, and glibcs without the symbol can't fulfil that
version, even though the weak symbol is the only thing we need from that
version.
This means the check_binary changes in bug 1634204 are too
relaxed, so we revert them (although we keep the easier to read
conditions in check_dep_versions).
We also introduce a hack in stdc++compat.cpp (although it's not
technically entirely about libstdc++ compat) so that we avoid the weak
symbol reference while keeping the intended baseline for libstdc++ and
glibc.

In adcd026838, conversions from `StringRef` to `std::string` became `explicit`.
The NFC fix would be to wrap the conversions in `std::string(...)` but since these are all short-lived uses for things like string compares, I've refactored a bit to keep them in native form.

I wrote this patch to address two problems:
1. if I do `mach run` from a directory other than $topsrcdir, $objdir, or
$objdir/dist/bin, then .gdbinit will not be loaded.
2. Debugging the firefox binary will never load the JS prettyprinters in any
case.
I believe this patch fixes other problems as well, such as .gdbinit_python not being found, and the gdbpp pretty-printers not getting loaded in various situations.
The main changes of this patch are:
1. Move .gdbinit into build/ (and $objdir/build/) to delay it from getting
loaded until the search path is configured.
2. Move libxul.so-gdb.py into the correct directory.
3. Use either libxul.so-gdb.py or js-gdb.py to configure the correct
search path then load .gdbinit, and have .gdbinit load all of the
pretty-printers (Gecko and JS).
4. Use a single preprocessed file to configure the source directory. Use
relative paths within the objdir for everything else.

This brings the `android-build` image very close to other build
images, paving the way for it to be folded in completely. It also
makes us more resilient in the face of upstream service interruptions.

To avoid sending identifying information, common absolute paths are patched with placeholder values. For example, devs
may place their Firefox repository within their home dir, so absolute paths are doctored to be prefixed with
"<topsrcdir"> instead.
Additionally, any paths including the user's home directory are patched to instead be a relate path from "~".

Rather than always printing instructions at the end of the bootstrap phase, we will now create a mozconfig

For standalone JS builds there are three possibilities: no-NSPR (the default),
build NSPR, or use system NSPR.
This patch makes no-NSPR the default again when not overridden by --enable-nspr-build
or --with-system-nspr. This was likely regressed by bug 1641775.

clang_getAddressSpace was found as a clang 5.0+ API by comparing the "tools/libclang/libclang.exports" files in the clang source code.
"clang_getAddressSpace" exists for 5.0.0 and 10.0.0, but not for 4.0.1.

When not using --with-android-ndk, NDK root is `~/.mozbuild/android-ndk-r20`.
When building this NDK path, since we use `os.path.join`, so it may include "\"
as file separator on Windows host. Then some options such as `-gcc-toolchain`
become invalid path (ex. `C:/users/makoto.mozbuildandroid-ndk-r20/`..).
So we should replace file separator with "/".

When running |mach python| with python 3, it was failing when importing "enum", since it would get the python 2 backport. By making these packages only
available to python 2, we allow python 3 to import standard library packages properly.
