To reliably detect corrupt APK, this patch adds a GeckoLoader.verifyCRC
call to enable verification of CRC before extracting libs.

This patch builds upon the existing DLL services functionality:
1) We add code to obtain the name of the subject from the cert used to sign a
binary (if present). This code is added inside mozglue because in the future
we will be using this code from the DLL blocklist, which is also located
there.
2) We add annotation functionality that registers itself for DLL load events
and updates crash reporter annotations as new libraries are loaded. It also
annotates any existing libraries that are also in memory at the time that the
CertAnnotator is first instantiated. This all happens off main thread, with
the exception of actually making the annotation when in a child process.

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.

Because one entry point is simpler than two, we make replace_init fulfil
both the roles of replace_init and replace_get_bridge.
Note this should be binary compatible with older replace-malloc
libraries, albeit not detecting their bridge (and with the
previous change, they do not register anyways). So loading older
replace-malloc libraries should do nothing, but not crash in awful ways.

The allocator API is a moving target, and every time we change it, the
surface for replace-malloc libraries grows. This causes some build
system problems, because of the tricks in replace_malloc.mk, which
require the full list of symbols.
Considering the above and the goal of moving some of the replace-malloc
libraries into mozglue, it becomes simpler to reduce the replace-malloc
exposure to the initialization functions.
So instead of the allocator poking into replace-malloc libraries for all
the functions, we expect their replace_init function to alter the table
of allocator functions it's passed to register its own functions.
This means replace-malloc implementations now need to copy the original
table, which is not a bad thing, as it allows function calls with one
level of indirection less. It also replace_init functions to not
actually register the replace-malloc functions in some cases, which will
be useful when linking some replace-malloc libraries into mozglue.
Note this is binary compatible with previously built replace-malloc
libraries, but because those libraries wouldn't update the function
table, they would stay disabled.

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.
