On most systems where we compile e2fsprogs, the u64 type is an
unsigned long long. However, there are platforms (such as the
PowerPC) where a long 64-bits and so u64 is typedef'ed to be unsigned
long instead of a unsigned long long. Fix this by using explicit
casts in printf statements. For scanf calls, we need to receive the
value into a unsigned long long, and then assign it to a u64, after
doing range checks.

Print inode numbers as unsigned values, to avoid printing negative
numbers for inodes above 2B.
Flags should be printed as hex instead of signed decimal values.

In response to reviewer comments, commit fe56188b07 included changes
that modified some of the code used to output error messages when
checking user-supplied block numbers. These changes converted calls
to parse_ulonglong() to calls to strtoblk(). Because strtoblk() calls
parse_ulonglong(), and both output error messages, two redundant and
relatively generic messages were output on each error.
Fix this by removing the error message output from strtoblk(), and
extending it to accept an optional error message argument that it
supplies in lieu of a default to parse_ulonglong(). Also, revert to
the more descriptive original error messages with mods per reviewer
comments, and fix an error message in do_replace_node().

Mostly by adding static and removing excess extern qualifiers. Also
convert a few remaining non-ANSI function declarations to ANSI.

debugfs should use strtoull wrappers for reading block numbers from
the command line. "unsigned long" isn't wide enough to handle block
numbers on 32bit platforms.

The extent_inode commands split_node, replace_node, and insert_node
take arguments which resulted in confusing error messages after
succeeding. Fix this.

Fix the missing function prototypes from the recently added new
debugfs commands, plus some signed vs unsigned comparison complaints.
Also change the abbreviation of the block_dump command from "bp" to
the more appropriate "bp".

This commit adds the functionality which had previously only been in
the tst_extents command to debugfs. The debugfs command extent_open
will open extent tree of a particular inode, and enables a series of
commands which will allow the user to interact with the extent tree
directly. Once the extent tree is closed via extent_open(), these
additional commands will be disabled again.
This commit exports two new functions from lib/ext2fs/extent.c which
had previously been statically defined: ext2fs_extent_node_split() and
ext2fs_extent_goto2().
