9e20465fd1 [thin-repair, thin_dump] When repairing we now hunt for the best btree roots.
We've had a trickle of users who accidentally activate the same pool on a
VM and host at the same time.  Typically the host doesn't do any IO, but
the kernel will still rewrite the superblock on shutdown.  This leaves
the superblock pointing to very out of date btree roots and so we get
massive metadata loss.

This patch changes thin_repair, and thin_dump --repair.  They now hunt
for the most recent, undamaged and consistent roots of the device and
mapping trees, and use that as the starting point of the repair.

de7c9a5781 [thin_journal_check] Checks journal of block manager activity.
You need to apply doc/bm-journal.patch to create the journal.

thin_journal_check confirms that if the machine had crashed at any time
during the test run no metadata corruption would have occured.

9311aa6483 fix compile failed with libc musl (#103)
There is a failure while compiling with libc musl:
[snip]
|./block-cache/io_engine.h:18:17: error: expected
unqualified-id before numeric constant
|  unsigned const PAGE_SIZE = 4096;
[snip]

The musl defeines macro PAGE_SIZE, undef it conditionally
could fix the issue.

1311447a94 [build] Include boost/optional/optional_io.hpp in thin-provisioning/emitter.h (#102)
This fixes following build failure with Boost 1.67.0:

   ^~~~~~~~~~~~~~~~~~~~~~~

boost/optional/optional_io.hpp exists since at least Boost 1.34.0, so it is
 safe to include in older versions, too.

6a7351da0d Fix musl build (#96)
a) Fix build if limits.h provides definition for PAGE_SIZE, as musl does w/musl per XSI[1] although it's apparently optional [2].
   This value is only provided when it's known to be a constant, to avoid the need to discover the value dynamically.
b) If not using system-provided (kernel headers, or libc headers, or something) use the POSIX approach of querying the value
   dynamically using sysconf(_SC_PAGE_SIZE) instead of hardcoded value that hopefully is correct.
