turns out that flushing the ids together with the ProFile cache was an
abysmal idea, as the latter expires after a few seconds after loading
the project, while references to the ProFiles (and thus the underlying
file ids) are kept for as long as the project stays loaded. the early
flush would cause re-use of the file ids, which would wreak all kinds of
havoc when re-loading projects.
but just ref-counting the vfs class is insufficient as well, as then the
ProFile cache (which expires after a timeout) could outlive all VFS
instances and thus refer to ids which were discarded and later re-used.
so we ref-count, and additionally let the cache instance hold a
reference to the vfs class.
this is sync-up with qt creator; no actual effect on qmake itself.

Thanks to QTBUG-61373, this qmake function was called with
/usr/local/5.10.1 as baseDir, which isn't absolute, leading to an
assertion failure. We could raise the error within qmake but it
proved easier to simply resolve any non-absolute baseDir using PWD,
before trying to use it as an absolute path.
Did the same for $$absolute_path(). Documented both. Adjusted the
assert that caught this to report any non-absolute path that upsets
it. Added simple tests, fixed an existing test.

For Q_OS_WIN, a path is only truly absolute if it includes a drive
letter; merely starting with a slash is not enough. (We can't support
UNC paths, so don't even try: qmake runs various commands in the
source directory using CMD.exe, which doesn't support UNC as PWD.)
This requires, when resolving a path relative to a root, transcribing
the root's drive to such not-quite-absolute paths.
Changed QMakeGlobals, $$absolute_path() and $$relative_path() to now
use IoUtils::resolvePath() rather than delegating to QDir's absolute
path method, since that doesn't correctly recognize the need for a
drive letter (and qmake did run into problems with some paths, from
splitPathList and a failing test, as a result).
Moved existing ioUtils tests for handling of relative / absolute paths
out into separate functions and expanded significantly. Fixed some
existing tests to use an absolute path where one is needed; added two
tests involving driveless (but rooted) paths; and fixed the test init
to set a value for QT_HOST_DATA/src property (the lack of which lead
to an assertion failure with this fix).
