Message:

Merge from lp:~jakub/helenos/vfs-2.5-cherrypick

This merge cherry-picks some of the changesets from Jiri Zarevucky's:

lp:~zarevucky-jiri/helenos/vfs-2.5

and then continues independently, yet sometime in a similar vein.

Roughly speaking, Jiri's branch is merged entirely up to its revision
1926 and then cherry-picked on and off until its revision 1965. Among
these changes are:

• relativization of the API,
• client-side roots,
• server-side mounts,
• inbox for passing arbitrary files from parent to child,
• some streamlining and cleanup.

Additional changes include:

• addressing issues introduced by the above changes,
• client-side I/O cursors (file positions),
• all HelenOS file system APIs begin with the vfs_ prefix and can be used after including vfs/vfs.h,
• removal of some POSIX-ish headers and definitions,
• additional cleanup.

• uspace/app/bdsh/exec.c (modified) (4 diffs)
