e2fsck: update quota when optimizing the extent tree
If quota is enabled, optimizing the extent tree wouldn't update the
in-memory quota statistics, so that a subsequent e2fsck run would show
that the quota usage statistics on disk were incorrect.

e2fsck: clean up feature test macros with predicate functions
Create separate predicate functions to test/set/clear feature flags,
thereby replacing the wordy old macros. Furthermore, clean out the
places where we open-coded feature tests.

e2fsck: rebuild sparse extent trees & convert non-extent ext3 files
Teach e2fsck to (re)construct extent trees. This enables us to do
either of the following: compress a highly sparse extent tree into
fewer ETB blocks; or convert a ext3-style block mapped file to an
extent file. The reconstruction is performed during pass 1E or 3A,
as detailed below.
For files that are already extent based, this algorithm will
automatically run (pending user approval) if pass1 determines either
(1) that a whole level of extent tree will fit into a higher level of
the tree; (2) that the size of any level can be reduced by at least
one ETB block; or (3) the extent tree is unnecessarily deep. It will
not run at all if errors are found and the user declines to fix the
errors.
The option "-E bmap2extent" can be used to force e2fsck to convert all
block map files to extent trees, and to rebuild all extent files'
extent trees. After conversion, files larger than 12 blocks should be
defragmented to eliminate empty holes where a block lives.
The extent tree constructor is pretty dumb -- it creates a list of
leaf extents (adjacent extents are collapsed), marks all indirect
blocks / ETB blocks free, installs a new extent tree root in the
inode, then loads the leaf extents into the tree.
