Under some unknown circumstances, debuggerd could become unresponsive.
If you try and take a bugreport during this time, it will hang forever.
Adding functions that have a timeout will allow dumpstate to stop if
dumping is taking too long.

Packets captured and logged by the NFLOG target are unicast, so
extend to catch and decode them. To avoid escaping issues, the raw
contents are passed around as hex strings.

This works around a bug on on 64 bit kernels + sdcard daemons
where we were using memory addresses as inode numbers.

In a scenario in which an on-line (blocking) client is running and
a clean is attempted (logcat -c), the following can be observed:
1) the on-line logger seems to freeze
2) any other clear attempt will have no effect
What is actually happening:
In this case prune function will "instruct" the oldest timeEntry
to skip a huge number (very close to ULONG_MAX) of messages, this
being the cause of 1.
Since the consumer thread will skip all the log entries, mStart
updating will also be skipped. So a new cleaning attempt will have
the same oldest entry, nothing will be done.
Fix description:
a. keep a separated skipAhead count for individual log buffers (log_id_t)
LogTimeEntry::LogTimeEntry
LogTimeEntry::FilterSecondPass
LogTimeEntry::skipAhead
LogTimeEntry::riggerSkip_Locked
b. update LogTimeEntry::mStart even if the current message is skipped
LogTimeEntry::FilterSecondPass
c. while pruning, only take into account the LogTimeEntrys that are monitoring
the log_id in question, and provide a public method of checking this.
LogTimeEntry::isWatching
LogTimeEntry::FilterFirstPass
LogTimeEntry::FilterSecondPass
d. Reset the skip cont befor the client thtread starts to sleep, at this point
we should be up to date.
LogTimeEntry::cleanSkip_Locked
LogTimeEntry::threadStart

/dev/pmsg0 used to record the Android log messages, then
on reboot /sys/fs/pstore/pmsg-ramoops-0 provides a means
to pull and triage user-space activities leading
up to a panic. A companion to the pstore console logs.

This is not available for host builds because OSX doesn't have
pthread_mutex_timedlock() or equivalent.

If verity is enabled and the underlying block device is marked
read-only, disable-verity fails. We cannot use the existing code
for enable-verity to make the device writable as the device in
/proc/mounts will be the verity device instead of the underlying
device we want to change. This change makes the correct device
writable when altering verity state.
