If this check fails and an OTA or mainline module update has recently
happened, we want to rollback the recent change. The easiest way to
handle this is to reboot, which will trigger the fallback mechanisms
that are already in place.

Add a property ro.boottime.init.first_stage to provide us a
first stage init duration from start to exec completed in
nanoseconds.
For consistency, report nanoseconds duration for
ro.boottime.init.selinux as well instead of milliseconds.
Now also report consistently from start to exec completed
instead of just the selinux load time.
SideEffects: ro.boottime.init.selinux is reported to TRON and
may alarm with the millionfold increase in precision.
ro.boottime.init is now also consistent with ns
precision.

If the matching string contains a [, \ or *, then it is also checked
with a regex match. Exact match is always tried firsts. If we do
not find an exact string match, switch to iterate through the entire
list for regex strings to find a match.
This allows us to scale with details without consuming a large
number of enums, permitting details that we do not necessarily want
resolution on to propagate to TRON. The hierarchical nature of the
boot reason <reason>,<subreason>,<detail>... can cause scenarios
where the <detail> does not matter to TRON, but does matter to
bugreport collection.
Add a bootstat --boot_reason_enum function to expose and test the
kBootReasonMap matchihg algorithm.
Add a kBootReasonMap test that exhaustively tests all built-in
entries, and an example of one regex entry. New regex entries added
to bootstat.cpp will need a series of exact match examples added into
filter_kBootReasonMap() function.

To ensure a surprise reboot does not take the last boot reason on
face value especially if coming from more than one boot sessions ago.
We shift and clear the value from persist.sys.boot.reason to
sys.boot.reason.last and establish a correct last reboot reason in
the canonical sys.boot.reason property.
This effectively deprecates persist.sys.boot.reason as an API. They
should have been using sys.boot.reason instead for a correctly
determined reasoning.

This change removes the CAP_SYSLOG file based capability from bootstat,
since the intention is that it should not be accessing the logs in the

CAP_SYSLOG has also been removed.

(partial cherry pick from commit fe3e762b6d)
Adding the boot sequence reported atom in ag/3518079 caused the duration
of bootstat to increase, as seen in b/72864061. I isolated the cause
down to calling BootReasonStrToReason. However, this function also gets
called in ReportBootReason, so I created another function that does the
parsing and sets the system boot reason property, and made
RecordBootReason and statsd logging get that property.
