modinfo: handle arguments more carefully
A simple case of breakage before this commit:
$ touch aes
$ modinfo aes
filename: /tmp/aes
ERROR: could not get modinfo from 'aes': Invalid argument
Add a new is_module_filename() function that attempts to do more than
just check if the passed argument is a regular file. We look at the name
for a '.ko' string, and if that is found, ensure it is either at the end
of the string or followed by another '.' (for .gz and .xz modules, for
instance). We don't make this second option conditional on the way the
tools are built with compression support; the file is a module file
regardless and should always be treated that way.
When doing this, and noticed in the test suite output, we open the
system modules index unconditionally, even if it is never going to be
used during the modinfo call, which is the case when passing module
filenames directly. For only one module there's not much advantage in
pre-loading the index, so just remove the call to kmod_load_resources().

Fix unaligned memory access in hash function
Use a function to properly get an unsigned short from memory that is
possibly unaligned.
Note that it implicitly fixes a small bug in the hash function that
was introduced when modifying the eina code: the line "hash ^= key[2]
<< 18;" is supposed to be accessing the 3rd byte of the remainder of
the input, but when 'it' was introduced, 'key' ('data' in eina code)
was no longer incremented, so this ended up accessing the 3rd byte of
the input from the beginning. This is fixed by iterating over 'key',
like the eina code does.
Before this patch depmod was failing on ARMv5 and possibly others that
don't have unaligned access. They do not calculate correctly the
dependencies as shown below:
[root@alarm ~]# modinfo bridge
filename: /lib/modules/2.6.39.4/kernel/net/bridge/bridge.ko
version: 2.3
license: GPL
srcversion:
6B583530AE2B39C7E2317BF

[root@alarm ~]# depmod
[root@alarm ~]# cat /lib/modules/2.6.39.4/modules.dep |grep bridge
kernel/net/bridge/bridge.ko:

See how modinfo properly lists the dependencies, but modules.dep which
depmod generates does not contain them. As a result, most kernel
modules fail to load because their dependencies are not loaded by
modprobe.

Check if struct stat has mtim member
Not all libc's have a mtim member in struct stat (dietlibc doesn't).
Change ts_usec() to receive a struct stat as parameter and implement it
accordingly for both cases.

modprobe: flush stdout before dumping indexes
Index dump doesn't use stdio.h function and instead call write()
directly on STDOUT_FILENO file descriptor. Therefore we need to flush
stdio buffers before calling it, to be sure the configuration dump will
appear before index's.
