Compare Pss of tested library in VerifyMemorySaving
DlExtRelroSharingTest.VerifyMemorySaving verifies whether
android_dlopen_ext(ANDROID_DLEXT_USE_RELRO) really saves memory.
This patch compares Pss of the tested library rather than total
Pss of the process, in case different behavior of dlopen() and
android_dlopen_ext() introduces random Pss usage.
Test: DlExtRelroSharingTest.VerifyMemorySaving

loader: enable loading libraries from tmpfs
This change adds two tests for dlopen from temporary files.
1. One Uses memfd_create() can be used to load libraries directly
from memory. This requires relaxing namespace accessibility check
in order to make this work in isolated namespaces.
2. Another checks that open with O_TMPFILE works.

Do not unmap reserved region on dlclose
dlclose used to unmap the part of the reserved region
for ANDROID_DLEXT_RESERVED_ADDRESS that was neccessary
to map PT_LOAD segments. With this change dlclose
replaces mapped PT_LOAD segments with a PROT_NONE,
MAP_ANONYMOUS | MAP_NORESERVE.
Previously caller was unmapping the reserved region after
the failed dlclose which led to race condition when someone
else reused the region freed by dlclose but before the unmap
by the chromium code.

gets the offset of the shared library inside of the zip instead of
hard-coding the value.

Introduce anonymous namespace
The anonymous namespace is introduced to
handle cases when linker can not find the
caller. This usually happens when caller
code was not loaded by dynamic linker;
for example mono-generated code.

linker: don't pass dlextinfo to dependent loads
Don't pass the parent load's dlextinfo to dependent loads, since this
causes the linker to try to load the dependencies using the same
addresses/relro/fds/etc as the main library, which is never going to
work. This was how it worked before ae69a95 which broke this.

Test that relro sharing actually saves memory.
Spawn 20 child processes, have them all load the library, and compare
the total PSS used in the case where we use dlopen() and the case where
we use android_dlopen_ext() with relro sharing. We assume we will save
at least 10% of the memory; in practise this example saves 40% or more
so this should be a reasonable threshold.

Handle empty relro segment or incorrectly sized file.
If the file has no relro segment, the generated relro file will have
length 0, which caused mmap to fail. If the relro file has nonzero size,
but is too short (e.g. because it's for the wrong version of the
library), the linker would segfault while comparing the data. Fix both
these issues: don't try to map a zero length file, and don't try to
compare data that would be beyond the end of the file.
Improve test to explicitly generate two versions of the library: one
with -z relro, and one with -z norelro, so we can test both cases; also
explicitly test the case where the relro file has length 0.

Allow sharing the RELRO section via a file.
Add flags and a file descriptor to android_dlopen_ext() to allow writing
the RELRO section of the loaded library to a file after relocation
processing, and to allow mapping identical pages from the file over the
top of relocated memory in another process. Explicitly comparing the
pages is required in case a page contains a reference to a symbol
defined in another library loaded at a random base address.

Support loading libraries to a reserved address.
Add flags and parameters to android_dlopen_ext() to allow loading a
library at an already-reserved fixed address. If the library to be
loaded will not fit within the space reserved, then the linker will
either fail, or allocate its own address space as usual, according to
which flag has been specified. This behaviour only applies to the
specific library requested; any other libraries loaded as dependencies
will be loaded in the normal fashion.
There is a new gtest included to cover the functionality added.
