If there is a newer file than the last indexing or if a file is added or
removed from the project or system PCH we have to reindex the project and
maybe the system PCH.

The small string control block moved to the beginning, so it is more cache
local. The control block is cleanup too, so it should be easier to read.
The alignment is removed because it is creating to big holes.

Before the string was simply swapped with the other string which can lead
to an unexpected behavior for xvalues. Now the destructor of the source is
called and it is default initialized.
foo = std::move(bar);
bar would now hold the value of foo.

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.

You need to allocate the memory before you replace a smaller text with
a larger one. It has some overhead because you go two times over the text
but it is anyway not designed for a large text.

The bug was that we returned the new end() but not the old reallocated
after a reallocation of the memory. The return value is used to move the
string after the found sub string to the next found sub string to the
new position of after the replaced sub string. Because the new end moved
more to the right we moved a much bigger chunk of memory. So we
accessed memory outside of the allocated memory.
