This commit removes the soname filter from the namespace fallback link
from `runtime` to `system` in the vendor process. This fixes the
problem that vendor process might fail to load `libnetd_client.so`,
`libc_malloc_debug.so`, `libc_malloc_debug_leak.so`, and other libc
dependencies.
This commit also removes the namespace fallback link from `runtime` to
`default` in the vendor process. According to the comments in [1], the
original intention was to allow the access to `/system/${LIB}` not
`/vendor/${LIB}`. Furthermore, `com.android.runtime` suppose to work
without libraries from `/vendor/${LIB}`.

This reverts commit a0d9f2fd6c.
Original change: Needs to support e.g. app_process in "default" ->
libnativehelper in "runtime" -> platform libs in "default" -> libc etc in "runtime".
Always make sure to switch namespaces when switching library paths between
/system and the APEX, so that internal library dependencies in both
locations are loaded from their own directory. E.g. libc++ and libbase live
in both places, and their dependents must always load the version they were
compiled with.
This CL also adds a temporary workaround to not break hwasan builds
(b/121038155).

upon memory usage high(>log_buffer_size), logd will try to prune(erase) all those old log elements which have been read by all readers for reclaiming the memory. As such, a too slow reader will be a hinder to the success of the prune. Logd has to try to kick-out the slow-est reader when memory usage is really too high(>2 * log_buffer_size). But the kick-out operation is just a request to the reader and at what time the reader will exit is always uncertain, beyond control. Furthermore, if you kick-out reader-A, waiting for A to exit; then, another reader-B may come in; then A exit; and then you kick-out-B, waiting for B to exit; and then, ...loop for ever: yes, logd may find that there seems to be always a slow reader hinder its pruning. As we all know, that, logd will probably kick-out a slow reader(logcat), hence, indeed, almost all log capturing tools will try to re-connect logd immediately after it being kick-out-ed. Such retry makes the issue easy to happen. And, we observed that the reader thread may often be blocked by socket write operation, which hindering its exiting and hereby hindering the prune progress. We need gracefully shutdown socket to relieve it from blocking and eventually stop such disaster from happening.

Staging Manager is a high-level service (yet to be committed) that
manages multi-package sessions requiring a reboot to be applied, for
example if one of the packages is an APEX file. This directory will
contain the session data and the temporary copies of the packages.

file.cpp has a call to pread with an off64_t that gets truncated, and
mapped_file.cpp does similar with mmap.

Move some mounting functionalities from librecovery so that
other modules can also mount logical partitions correctly.
- Also, refactor to use C++ Fstab struct.
- Also, fixed CreateLogicalPartitions() to take full path of

Remove new line character ('\n') from the kernel command line after
reading from '/proc/cmdline'. This character is not contained in the
original string and is added as a result of reading (according to
kernel source codes [1]):
...
seq_puts(m, saved_command_line);
seq_putc(m, '\n');
...
As a result, this may corrupt the last argument of the string. For
example, if the last argument is 'androidboot.slot_suffix=_a', then the
target partition ('vendor_a\n') will not be found in fstab section of
the device tree.

This adds an option to list device mapper devices including their
current target table. Useful to be included in bugreport to
map the logical partitions metadata with actual device mapper setup.

This is a workaround to allow us to use libnetd_resolv.so from
the resolver APEX before b/120661824 is fixed.
We cannot put the APEX into the search path due to b/120661824,
but we can put it into the permitted path,
