*	logd: Fix pruning	TraianX Schiau	2015-01-14	1	-3/+5
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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 Change-Id: I1b369dc5b02476e633e52578266a644e37e188a5 Signed-off-by: TraianX Schiau <traianx.schiau@intel.com>

	* Create a new userspace log daemon for handling logging messages.
