[PATCH 0/7] Fix broken file paths on Win32

[Lubomir I. Ivanov]

these are the rebased series from yesterday.
includes thiago's suggestions and also the one
from jef about the redundant sqlite wrapper.

compiles ok on win32/linux. please, test osx,
but if there are issues on that let's send
a separate patch on top of the series, and if
possible.

the win32 issues seems to be solved, except that
we cannot ZIP_CREATE files in odd paths yet, but
i kinda do have a solution for that, but only
for users who have sane win32 (e.g. US-ASCII)
systemdirs.

pro-tip: don't rebase messy trees post midnight. :\
