Bug 1081034 part 3 - Resolve libc symbols with our linker. r=nfroyd
...
This allows to resolve weak symbols from some Android device's libc that
dlsym() won't. This is effectively an alternative fix to bug 791419, without
requiring wrapping symbols.

Bug 1081034 part 2 - Move initialization of self_elf to its own separate class. r=nfroyd
...
The new class is kind of like SystemElf, but using our linker's own symbol
resolution. This also adds some initialization from ELF program headers that
weren't done previously for self_elf, as well as registration as for CustomElf
instances.

Bug 1077384 - Make libmozglue a pseudo-LD_PRELOAD on android. r=nfroyd
...
In order to avoid adding more dlsym overhead than there already is, resolve
symbols directly in the library containing the linker. (GetSymbolPtr is
essentially free ; dlsym makes the system linker compule a ElfHash itself,
and that's quite expensive to do on all symbols)
This also paves the way for direct symbol resolution in all system libraries.

Bug 1036286 - Delay registration of the faulty.lib signal handler until when it's necessary. r=nfroyd
...
It's necessary to delay it because for the second part, we need to call dlopen,
and until recently bionic's linker dead-locked when using dlopen from a static
initializer.

Bug 1036286 - Make sure libraries loaded by faulty.lib use its own sigaction. r=nfroyd
...
Android L added a libsigchain library it LD_PRELOADs. That library exposes
a different sigaction than libc's. It's used for ART.
faulty.lib gets its sigaction from libsigchain, but after bug 874708, the
libraries it loads simply use libc's sigaction, assuming it would be the
hooked one. In turn, this means libraries loaded by faulty.lib may
override faulty.lib's handler, which is definitely not the intent.
This essentially restores some of the code that bug 874708 removed.
An alternative fix would be to add support for LD_PRELOAD, but that has more
implications and feels more risky. This could be done, if necessary, as a
followup.
