Allow read_tree_block() and read_node_slot() to return error pointer.
This should help caller to get more specified error number.
For existing callers, change (!eb) judgmentt to
(!extent_buffer_uptodate(eb)) to keep the compatibility, and for caller
missing the check, use PTR_ERR(eb) if possible.

Since orphan extents are handled in previous patches, now just punch
holes to fill the file extents hole.
Also since now btrfsck is aware of whether the inode has orphan file
extent, allow repair_inode_no_item() to determine filetype according to
orphan file extent.

In some fs tree leaf/node corruption case, file extents may be lost, but
in extent tree, its record may still exists.
This provide the possibility for such orphan file extents to be
recovered even we can't recover its compression and other info, we can
still insert it as a normal non-compression file extent.
This patch provides the repair and report function for such orphan file
extent.
Even after such repair, user may still need to try to decompress its
data if user knows that is a compressed extent.

Record every file extent discontinuous hole in inode_record using a
rb_tree member.
Before the patch, btrfsck will only record the first file extent hole by
using first_extent_gap, that's good for detecting error, but not
suitable for fixing it.
This patch provides the ability to record every file extent hole and
report it.

Add btrfs_get_extent() and btrfs_punch_hole() for btrfs-progs.
Btrfs_get_extent() will act much like kernel one, return the first
extent that covers the given range.
The difference will be that progs btrfs_get_extent() can't handle
no-holes feature, which means caller should handle it carefully.
Btrfs_punch_hole() will punch a hole in given range of given inode,
however it differs from kernel one since it won't zero any page or drop
any extents if there is any extent in the hole range.
These functions are mainly used for later I_ERR_FILE_EXTENT_DISCOUNT
repair function.

Before this patch, when a extent's data ref points to a invalid key in
fs tree, this happens if a leaf/node of fs tree is corrupted, btrfsck
can't do any repair and just exit.
In fact, such problem can be handled in fs tree repair routines, rebuild
the inode item(if missing) and add back the extent data (with some
assumption).
So this patch records such data extent refs for later fs tree recovery
routine.
TODO:
Restore orphan data extent refs into btrfs_root is not the best
method. It's best to directly restore it into inode_record, however
current extent tree and fs tree can't cooperate together, so use
btrfs_root as a temporary storage until inode_cache is built.

- define basic default CFLAGS in configure.ac, because:
* autoconf default is -g -O2, but btrfs uses -g -O1
* it's better to follow autoconf; standard way to modify
CFLAGS is to call: CFLAGS="foo bar" ./configure
- move all flags to one place in Makefile.in
- don't use AM_CFLAGS, the CFLAGS and STATIC_CFLAGS are enough
- don't mix objects and flags in $LIBS, it's more readable to

The current approach to option parsing, where long-only options are
selected on the basis of their position in the long_options array is
fragile and painful to modify if options are to be inserted into the
list, rather than appended.
Instead, use the last field of struct option to return a value which
cannot be a char (and hence a short option), and simply switch on those
within the case statement.

glibc 2.10+ (5+ years old) enables all the desired features:
_XOPEN_SOURCE 700, __XOPEN2K8, POSIX_C_SOURCE, DEFAULT_SOURCE; with a
single _GNU_SOURCE define in the makefile alone. For portability to
other libc implementations (e.g. dietlibc) _XOPEN_SOURCE=700 is also
defined.
This also resolves Debian bug report filed by Michael Tautschnig -
"Inconsistent use of _XOPEN_SOURCE results in conflicting
declarations". Whilst I was not able to reproduce the results, the
reported fact is that _XOPEN_SOURCE set to 500 in one set of files
(e.g. cmds-filesystem.c) generates/defines different struct stat from
other files (cmds-replace.c).
This patch thus cleans up all feature defines, and sets them at a
consistent level.
