Sometimes when endpoint_alloc returns ENODEV,
max_rw will end up being a value that is too
big.

These two Soong product_variables were usually controlled by
ENABLE_CPUSETS and ENABLE_SCHEDBOOST in BoardConfig.mk. This change
turns the build time variables into runtime decision by checking if
a special file, "tasks", can be found under the mount points,
/dev/cpuset and /dev/stune, for cpusets and schedboost, respectively.
That special file only exists when the corresponding Linux kernel
configurations, CONFIG_CPUSETS and CONFIG_SCHEDTUNE, are set.
Bug: 34726944
Test: Tested on Sailfish with following configurations
neither cpuset nor schedtune enabled in the kernel
cpuset enabled, but schedtune disabled in the kernel
both cpuset and schedtune enabled in the kernel

The .clang-format is a symlink to ../init/.clang-format, which is merged
recently. As init is the major user of fs_mgr, it's better to keep the
style consistent.
Only recent newly-added files written by me are formatted. For other
files, let's format them gradually to keep 'git blame' intact.

Supply a wrapper to the logcat API that provides some analogous

POSIX lets you choose whether or not SIGPIPE disposition is inherited,
and Linux chose "yes". Work around that.

We already check our /proc/`getppid()` fd every time we attach a thread, so
these were unneeded at best. The one that happened after dropping
capabilities was actively wrong, though, because /proc/pid access
checks happen on every operation. (only on some kernels?)
Also, add a check that getppid() doesn't change after opening
/proc/getppid().

snprintf isn't safe to call in the linker after initialization, because
it uses MB_CUR_MAX which is implemented via pthread_getspecific, which
uses TLS slots shared with libc. If the TLS slots are assigned in a
different order between libc.so and the linker, MB_CUR_MAX will
evaluate to an incorrect value, and lead to snprintf doing bad things.
Switch to __libc_format_buffer.
