Change the way cache hits and misses are tracked to avoid counting blind page writes as misses and count the results of partial page writes. Report cache hit rate in status.

Replace g_random and g_nondeterministic_random with functions deterministicRandom() and nondeterministicRandom() that return thread_local random number generators. Delete g_debug_random and trace_random. Allow only deterministicRandom() to be seeded, and require it to be seeded from each thread on which it is used.

Remove noexcept macro and replace with BOOST_NOEXCEPT.
...
BOOST_NOEXCEPT does what the noexcept macro was supposed to do, but in a
way that is correctly maintained over time.

Many bug fixes related to concurrent page operations and pager shutdown.

Many bug fixes. AsyncFileCached write() on a page with a zero-copy read in progress would orphan the old page before the read was finished. Pager file operations were not converting page id to int64 for byte offset calculation. Pager was not calling releaseZeroCopy() after readZeroCopy() if there was an error or cancellation. Pager reads were using some variables that could go out of scope. BusyPage's mechanism for notifying when a physical page is no longer in use is itself no longer in use and therefore removed. Pager shutdown now cancels all outstanding reads. Improved some debug output.

Adjust all includes to be relative to the root.
...
Remove the use of relative paths. A header at foo/bar.h could be included by
files under foo/ with "bar.h", but would be included everywhere else as
"foo/bar.h". Adjust so that every include references such a header with the
latter form.

Rewrite all `Void _ = wait(...)` -> `wait(...)`.

This takes advantage of the new actorcompiler functionality to avoid
having duplicate definitions of `Void _` when trying to feed the
un-actorompiled source through clang.

AsyncFileCached now allows writing and truncation of whole pages previously read using readZeroCopy and not yet released without prior readers seeing the effects of the write.

Attempt to normalize trace events:
...
* Detail names now all start with an uppercase character and contain no underscores. Ideally these should be head-first camel case, though that was harder to check.
* Type names have the same rules, except they allow one underscore (to support a usage pattern Context_Type). The first character after the underscore is also uppercase.
* Use seconds instead of milliseconds in details.
Added a check when events are logged in simulation that logs a message to stderr if the first two rules above aren't followed.
This probably doesn't address every instance of the above problems, but all of the events I was able to hit in simulation pass the check.

Bug (arguable, perhaps) fix in AsyncFileCached. Order was not being enforced between writes and truncates such that calling and waiting on a truncate to X and then writing to X + 1 could end up writing first and then truncating the written page off of the file.
