libstdc++ support is broken after moving to moz.configure. No one uses this option and NDK will remove GCC, so we should remove this and --with-android-cxx-stl option.

This option was added ~decade ago; AFAICT from bug archaeology, the
option was added to prevent our servers from being overwhelmed.
Somewhere over the years, however, we obtained more capable servers and
the option disappeared from mozconfigs. It seems moderately unlikely
that we'll have a need for this option again, and we could reintroduce
this patch very easily in any event. Let's go ahead and remove it.
The -fsanitize=integer analysis from UBSan can be helpful to detect signed and unsigned integer overflows in the codebase. Unfortunately, those occur very frequently, making it impossible to test anything with it without the use of a huge blacklist. This patch includes a blacklist that is broad enough to silence everything that would drain performance too much. But even with this blacklist, neither tests nor fuzzing is "clean". We can however in the future combine this with static analysis to limit ourselves to interesting places to look at, or improve the dynamic analysis to omit typical benign overflows.
It also adds another attribute that can be used on functions. It is not used right now because it was initially easier to add things to the compile-time blacklist to get started.
Finally, it includes a runtime suppression list and patches various parts in the test harnesses to support that. It is currently empty and it should not be used on frequent overflows because it is expensive. However, it has the advantage that it can be used to differentiate between signed and unsigned overflows while the compile-time blacklist cannot do that. So it can be used to e.g. silence unsigned integer overflows on a file or function while still reporting signed issues. We can also use this suppression list for any other UBSan related suppressions, should we ever want to use other features from that sanitizer.

old-configure does not support being passed them as command line
arguments, so we have to pass them through the environment.

Importing 'os' in python configure functions, on Windows, changes the
separate the various os.path functions use, and that can have
unexpected, badly handled, consequences. While on the long term, it is
desirable to make @imports('os') modify os.path to use the same base
functions as if there were no @imports, let's go with the simpler
workaround of restoring the non-{isfile,isdir,exists} os.path functions
from b6be0e9e3e1e.

We want functions without an @imports to not have any side effects, and
to not use external resources. So remove the few functions we expose from
os.path without @imports('os') that do.

This patch introduces a small change in behavior: we now unconditionally
require libffi > 3.0.9 when using system ffi, rather than accepting 3.0.9
when using GCC, as 3.0.10 was released 5 years ago, and should be widely
available.
