49ce6d0741 Remove libkmod-loaded.c and re-order functions in libkmod-module.c 
It's not possible to move functions related to "live" modules to
libkmod-loaded.c because they depend on the definition of kmod_module.
Putting this structure in the private header is not a good idea, so let
all functions related to "live" information in the end of
libkmod-module.c, and move the sole function from libkmod-loaded.c to
this place. This way all functions get the right documentation
about their sections.

c35347f15c coding style: fix lines over 80 chars 
Lines should not go over 80 chars with a few exceptions:
	- headers

	- long strings, otherwise we break grep

This should go later in a coding-style file

cb8d4d3e99 API-BREAK: kmod_new() takes a second parameter for configuration directory.

bd3f553526 export module's options and commands. 
This will be required to implement modprobe later. The implementation
follows "man modprobe.conf" and allows options to be specified for
alias as well, thus the need for kmod_resolve_alias_options().

Example mod-a.conf:

    options mod-a a=1 b=2
    options mod-a c=3
    alias mymod-a mod-a
    options mymod-a d=4

Results in:
    options mod-a a=1 b=2 c=3
    options mymod-a a=1 b=2 c=3 d=4

Install commands are being concatenated with ";", but manpage is not
clean about this behavior.

d091546448 index-mm: allocate values inline into node, strings points to mmap. 
For mmap mode, we can avoid allocating and copying strings from the
mmap'ed memory.

With that we have fixed length "struct index_mm_value" that can be
allocated inline with "struct index_mm_node".

fc2d835df5 index-mm: fix memory access. 
uint32_t reads must be aligned, they're not then use memcpy().

read_alloc_chars_mm() and read_chars_mm() were wrong, normalize all
address calculation using single byte pointer "addr" that is
incremented by the amount read, this will avoid further errors.

405f614af9 index: improve buffer management and reduce mallocs. 
Grow buffer based on a step, avoiding hitting the system over and over
again.

Do not allocate the 'struct buffer' as in all cases the lifetime is
known and the pattern was allocate then free in every call site.

e005facdb9 Only search path in moddep if it's not already set 
rmmod/insmod should be able to operate directly on files, not relying on
indexes and configuration.

$ cd /lib/modules/$(uname -r)/kernel
$ # try to insert module giving a relative path
$ insmod drivers/acpi/ac.ko
