Calling libusb_reset_device() resets the usb connection with device
on linux platform. It can interfere with other usb interfaces and only
works on linux.
Removing it only affects when adb server is killed while doing IO with
device, which will be solved in later patches.

logcatd is the same as logcat, except that the -L flag, if supplied,
runs once, then the command re-runs itself without the -L flag with
the same argument set. By introducing a logcatd daemon executable
we can solve the problem of the longish reads from pstore that
sometimes occur when the system is excessively busy, starving this
background cgroup daemon as we absorb the delay in a backgrounded
init "service", rather than in a forgrounded init "exec". This would
not have been efficiently possible without the introduction of
liblogcat.
There are no doubt many flags that make no sense to run twice with,
and without, the -L flag. In the general sense we expect the caller
to perform the correct set of operations and not pick these nonsense
operations. logcatd is only supplied on engineering and debug builds
for logpersist, and is only an automated aid to triage.

If -h or --help argument was supplied, logcat would report the help
message but also return an error. Officially add -h and --help as
recognized flags, report all help with a (zero) success error code.
Adding this, and the associated test, was split off as a stepping
stone to resolving an issue with logcat -L or --last flag operations.

this will make the implementation more cleaner,
and has error message output when failed on some operations
also add the O_TRUNC flag explicitly for the open function
called in write_file.
And add more test on read_file and write_file functions

The content parameter of write_file() previously took a char* that was
then converted to a std::string in WriteStringToFd(). One unfortunate
effect of this, is that it is impossible to write data that contains
'\0' within it, as the new string will only contain characters up
until the '\0'.
This changes write_file() to take an std::string, such that
std::string::size() is used to determine the length of the string,
allowing it to contain null characters.
Also change the path parameter of read_file() and write_file() for
consistency.
Lastly, add a test for handling strings with '\0' in them.

This reverts commit 82f8bb785e.
Sadly, we'd have to extend CAP_SYS_RESOURCE to a bunch of execution
domains to make this work, which isn't feasible.

Filesystems like ext4 allow the setting of the "resgid" parameter
to designate a GID that is allowed to use the "reserved" disk space
(in addition to UID 0). We'll be granting this GID to critical
system processes, so that the system is usable enough for the user
to free up disk space used by apps.

Failed to acquire BM_log_print_overhead as it was renamed from
BM_log_overhead in commit 8f2492f582
(liblog: benchmark: Use local LOGGER_NULL frontend')
The test report would not clearly identify which entry was missing, or
unparsed, so unrolled the loop and incorporating the indexes by name
so that gTest failure report offers a much better clue to the problem.
