cleanup mkdir usage with boost filesystem:

Replaced copy/pasted code and MKDIR_TAKES_ONE_ARG #ifdefs
with portable boost filesystem path and directory creation.

Gets the correct home directory on windows systems: APPDATA.
Replaces large amounts of copypasta with single lines of code.
Removes MKDIR_TAKES_ONE_ARG configuration checks from m4 files.
Adds boost filesystem and system library as build dependencies.
