In current git there is a double free on ctx->filesystem_name in the
end of main() and in e2fsck_free_context, causing e2fsck to abort at
the end of pass5.

Provide mke2fs with a much more sophisticated system for controlling
configuration parameters of a newly created filesystem based on a
split filesystem and usage type system. The -t option to mke2fs was a
deprecated alias to -c; it now specifies a filesystem type (ext2,
ext3, ext4, etc.), while the -T option can now be a comma separated
usage list.

The m_no_opt test has been silently failing since the addition of
mke2fs.conf, since it was trying to use resize_inode on a non-sparse
filesystem. Fix it so it works correctly.

Thanks to Max Lindner (lokimuh) for pointing this out.
I'm playing around a bit with ext2 and multi-user encryption and I
need space for my key management. So I set s_first_data_block to 4000
or something like that.
This way mke2fs segfaults when executing
ext2fs_create_resize_inode() because
blk_t goal = 3 + sb->s_reserved_gdt_blocks + fs->desc_blocks +
fs->inode_blocks_per_group;
will produce a integer underrun later and segfault then in the
ext2fs_test_bit assembler inline function.
when exchanging 3 with 2 + sb->s_first_data_block, mke2fs does not
segfault.
I'm not 100% sure if thats the correct way dealing with this issue
but I think its a proper solution.

Some library makefiles use $(LIB)/$(LIBRARY).a as a dependency for the
static library built by the makefile fragment. Add it as a target
created when building $(LIBRARY).a so that it is rebuilt when necessary.

Extent data is shared with the i_block[] space in the inode,
but it is always swapped on access, not when the inode is read.
In e2fsck/pass1.c we must be careful when checking validity
of the extents flag on the inode. If the flag was set when
the inode was read & swapped, then the extents data itself
(in ->i_block[]) was NOT swapped, so testing for a valid
extent header requires some swapping first. Then, if we
ultimately set the extents flag, all of i_block[] must be
re/un-swapped.
This passes the f_extent regression test on both ppc & x86.

Add a check for the UNINIT_BLOCKS flag set in the last group. The kernel
patch doesn't handle this gracefully, because it assumes there are a full
set of blocks in each group marked UNINIT_BLOCKS. The kernel should be
fixed up, but in the meantime this avoids hitting the problem, and is
more consistent with lazy_bg not marking the last group UNINIT.

Split the m_lazy testcase into two tests - one that has resize enabled,
and one that does not. There were previously problems with lazy+resize
because the resize feature consumed blocks in some of the groups.

Previously, fsck was only passing in -Cn to the first e2fsck process
to start up, and enabling the progress information by sending a
SIGUSR1 signal. This didn't work if the progress information was
intended to go to file descriptor, since the information was never
passed to e2fsck.
So we now pass the progress fd in as a negative number if the progress
information is intended to be initially suppressed.

The exiting fsck instance wasn't marked as DONE, so the safety checks
thought a progress bar was still in progress, and so we didn't enable
another filesystem's checking.

We need to set tm_isdst to -1 so that mktime will automatically
determine whether or not daylight savings time (DST) is in effect.
Previously tm_isdst was set to 0, which caused mktime to interpret the
time as if it was always not using DST.

The ext2fs_extent_get() function was not OR-ing together UNINIT
and LEAF flags in the case where an extent was both; so if we
had an extent which was both uniint and leaf, pass1 would bail
out where depth == max_depth but was not marked as leaf, and
e2fsck (from the next branch) would abort with:
e2fsck 1.40.8 (13-Mar-2008)
Pass 1: Checking inodes, blocks, and sizes
Error1: No 'down' extent
Aborted
Also, if the error is encountered again, print the inode number
to aid debugging until it's properly handled, at least.
