With the goal of disallowing exit time destructors, SystemProperties's
non-trivial destructor needs to be removed. This means replacing the
union hack with yet another hack as we don't want to allocate anything
despite relying on some polymorphism.

Having any destructor with a global variable in bionic is causing
some issues. Since we don't actually need to munmap in this case, we
remove the destructor to work around that issue.
A small class is used to still munmap during tests.

If the mmap'ed file doesn't end in a new line, previously we'd leak
the mmap'ed region. This change now munmap's the region.

RTLD_NEXT/DEFAULT lookup should not skip handle lookup
in the case when the load group is RTLD_GLOBAL.
Note that there is a difference between load group is local group.
The local group includes externally referenced libraries where
the load group does not. The external reference in this context is a
DT_NEEDED library that belongs to a previously loaded group.

sigset_t and sigset64_t differ (arm, x86) and where they're the same
(all the rest).

Use the malloc debug framework to implement the malloc debug hooks
since it can introduce a performance issue.
Also, modify the bionic/tests/utils.h slightly to dump an error message
when the exe failed.

Test: Ran malloc hook unit tests.
Test: Ran malloc debug unit tests.
Test: Enabled malloc hooks and ran bionic unit tests and verified no
Test: unexpected failures.
Test: Enabled malloc debug and malloc hooks and verified malloc debug wins.
Test: Enabled malloc debug using env, property, and property with name
Test: still works.

Every other architecture already uses an assembly file here.
The previous code aligned ESP incorrectly, but it doesn't really matter
because everything is built with Clang's -mstackrealign, which realigns
ESP in every function prologue.

We now have a proper mechanism for OEMs to create new AIDs via
config.fs and /vendor/etc/{passwd,group}. This means that there is no
reason for OEMs to add AIDs by modifying android_filesystem_config.h,
and therefore we can add this check back.
Bug: 27999086
Test: pwd and grp tests pass with custom AIDs in config.fs
This reverts commit a14485adde.

sigset_t is already large enough on mips so use the same principle
as on LP64 architectures: typedef sigset_t sigset64_t
Also prevent accessing sa_restorer field for architectures which
don't define SA_RESTORER in signal_test.
This allows compilation of signal_test.
