- Adds some asserts in KAIO to ensure that when knob is set, we don't
end up using KAIO in any case.
- Fixes a bug where we initialize AsyncFileKAIO on Linux builds even
when KAIO is disabled. This can cause problems in systems such as
Windows Subsystem for Linux where KAIO is not supported.
FIXES#2382
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.

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.
* 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.
For situations in which we have support for FALLOC_FL_ZERO_RANGE, it's much
faster to use fallocate than manually overwrite the file with zero bytes. Note
that this support depends on having a kernel from late 2014 or newer, and being
on ext4 or xfs. If these conditions aren't met, we'll fall back to writing
zeros in 1MB chunks as normal.
