e2fsck: propagate number of threads

Sometimes, such as in orphan_inode case, e2fsck_pass1
is called after reading the block bitmaps. This results in
reading the block bitmap sequentially and multithreading
only gets kicked in later. Fix the thread count earlier
while setting up the file system.

e2fsck: misc cleanups for pfsck

Add -m option description to e2fsck.8 man page.

Rename e2fsck_struct fs_num_threads to pfs_num_threads to avoid
confusion with the ext2_filsys fs_num_threads field, and move
thread_info to be together with the other HAVE_PTHREAD fields.

Move ext2_filsys fs_num_threads to fit into the __u16 "pad" field
to avoid consuming one of the few remaining __u32 reserved fields.

Fix a few print format warnings.

e2fsck: print thread log properly

When multi-thread fsck is enabled, logs printed from multiple
threads could overlap with each other. The overlap sometimes
makes the logs unreadable because log_out() is used multiple times
for a single line.

This patch adds leading [Thread XXX] to each logs if multi-thread
is enabed by -m option.

This patch also adds message to show the group ranges and inode
numbers for each thread, which is useful for debuging multi-thread
check.

-C shouldn't be specified and the completion progress report won't

the implementation of multi-thread fsck in the future.

Completion progress support with multi-thread fsck will be added
back after multi-thread fsck implementation is finished. Right
now, disable it to simplify the implementation of multi-thread fsck.

mmp: do not use O_DIRECT when working with regular file

Currently the mmp block is read using O_DIRECT to avoid any caching that
may be done by the VM. However when working with regular files this
creates alignment issues when the device of the host file system has
sector size larger than the blocksize of the file system in the file
we're working with.

This can be reproduced with t_mmp_fail test when run on the device with
4k sector size because the mke2fs fails when trying to read the mmp
block.

Fix it by disabling O_DIRECT when working with regular files. I don't
think there is any risk of doing so since the file system layer, unlike
shared block device, should guarantee cache consistency.

resize2fs: prevent block bitmap warnings when doing extreme fs expansions

This commit fixes a bug where if a small file system is resized to
ridiculous sizes, such that the size of the resized block group
descriptor blocks exceed the original file system, and this would
result in resize2fs triggering a large number of scary warning
messages:

   Illegal block number passed to ext2fs_test_block_bitmap #12440
   for block bitmap for broken.img

This can be replicated via:

   ./misc/mke2fs broken.img -b 1024 -T default
   truncate -s +1500G broken.img
   ./resize/resize2fs broken.img

Fortunately, aside from triggering these warning messages, the bug had
no other bad effects.
