It was added in bug 683127 as a forced include for nspr, and
accidentally became unused after bug 1230117, but it turns out that all
versions of Android we care about nowadays (and probably back then) now
support dladdr.

When looping through the debugger helper links during our
dl_iterate_phdr implementation, we effectively race with other threads
dlclose()ing libraries while we're working.
We do have a (rather involved) check in place to ensure that elf headers
are readable. But it turns out in practice, some dlclose() do happen
between the check and the actual read of the elf headers.
Unfortunately, we can't lock the system linker while we're looping, so a
better approach is to only loop through the libraries we loaded, and
rely on the system dl_iterate_phdr to iterate over the (remaining)
system libraries.
Unfortunately (again), Android versions < 5.0 don't have a system
dl_iterate_phdr, so we have to rely on the old iterator when it's not
present.

We're going to introduce two code paths that need to fill dl_phdr_info
from different iterators, so first move the code to a separate class,
that both code paths will be able to call.

We already dealt with issues around dlsym not resolving weak symbols
with libc in bug 1081034. This fix applies the same workaround to libm,
which solves the isnanf issue.
The previous fix for looking up __isnanf is no longer needed.
The comment with the accompanying change explains things, but the short
version is that clang generates full calls to isnanf, which our
dlsym-based symbol lookup in the custom linker cannot handle correctly.
We therefore need to do extra work for isnanf to find the correct symbol.
Report init failure if uncompressed stream size is 0.
Check for overflows when casting.
Verify LZMA stream only has a single block.

We have a minimum requirement of VS 2015 for Windows builds, which supports
the z length modifier for format specifiers. So we don't need SizePrintfMacros.h
any more, and can just use %zu and friends directly everywhere.

The linker uses zlib. The linker is in mozglue, zlib is in libxul by
default. As a consequence, we made --with-system-zlib a requirement for
builds enabling the linker.
In the meanwhile, we added an option that makes zlib built in mozglue
for different needs, which, in fact, also allows to do that when the
linker is enabled.
So, allow to build without system zlib when the linker is enabled.

Since bug 1307886, we don't actually use szip anymore, and don't even
have the option to package Fennec using it. We can thus remove the
support for loading them, as well as on demand linkage.
The latter might mean we can remove the segfault handler, but it's
unclear whether this is currently working around other issues with
registering signal handlers, so we'll leave that to a followup.

This deprecates PYTHON_UNIT_TESTS and replaces it with PYTHON_UNITTEST_MANIFESTS.
In the build system, this means python unittests will be treated the same as all
other test suites that use manifestparser. New manifests called 'python.ini' have
been created for all test directories containing python unittests.

This removes the unnecessary setting of c-basic-offset from all
python-mode files.
This was automatically generated using
perl -pi -e 's/; *c-basic-offset: *[0-9]+//'
... on the affected files.
The bulk of these files are moz.build files but there a few others as
well.

There are two instances:
- MappableSeekableZStream::Create uses ScopedDeletePtr, which is
actually a little odd, since MappableSeekableZStream, as a Mappable,
is refcounted, and it's unusual to use two different kinds of smart
pointers for a single class. I think the more natural thing would be
for MappableSeekableZStream::Create to return an already_AddRefed, but
that change spirals out of the realm of "simple refactoring" quickly.
- SzipCompress::run uses ScopedDeletePtr along with some dubious use of
raw pointers. I changed things out for UniquePtr and also tidied the
memory management a bit, which I think makes things a little clearer.
The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
