The file name id must be unique for very entry, so the directory id must be
incorporated too. Now there is always one unique integer id for every
file path. The directory id is there to access and compare the directory
much faster but not provide any data to the uniqueness of the id.

The string cache is only very seldom written but very often read. To
improve thread scaling it is faster to lock it only for write operations.
So we use a shared mutex which is locked in shared mode for read
operations and locked exclusively for write operations.

The database is using file path integer ids to handle file paths because
otherwise we would save many redundant data. This patch is improving it
further with the introduction of a database based file path cache. The
entries are now divided in a directory path and file name. This is quite
handy for directory based file watching.

The old algorithm was comparing the string two times. One timer for smaller
and one for larger. And memcmp on a long string still costs. The new one
has a three state so it can compare smaller, greater and equal in one.
There is a reverse version too which has big advantage for file paths.

Compiling every header file again and again is quite time comsuming. There
are technics to improve this like preambles(a kind of automated
precompiled header) but they don't share their data between translation
units. This approach provides an automatically generated precompiled
header for every project and subproject to improve the loading time.
