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.

85132101e4 kmod_search_moddep: reorder to avoid creating path when not required. 
if we're using mmap'ed index, say so and avoid creating the path as it
won't be used.

3b2099595b fix snprintf usage. 
snprintf() takes the full buffer size, including \0 and guarantees it
will be there.

810803dbe8 Pass enum around instead of filename 
This will allow us to later use the index to search these indexes.

4272d08780 Do not allocate path for known places an close resource asap 
This place is not supposed to exceed PATH_MAX. So, use snprintf instead
of asprintf.

Close the index before iterating the values.

33bb69b943 Load and unload resources 
This call will mmap all the index files and in future some of the work
done in ctx creation can be put here.

a4a750297d Refactor index file handling 
Put all names in a static vector and declare a enum containing the
number of indexes. This way it's easier to create vectors inside ctx
that depend on these files.

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.

e18ad35c64 fix path handling at dependencies parsing. 
paths come relative to dirname, make them absolute to avoid confusion
later.

1bdd951ee2 log: give log function its data instead of kmod_ctx. 
This will be the most common use case for logging, also changed
log_stderr() to log_filep() with data being stderr to test it.

e1a6b30dc4 modname_normalize: fix const and buffer overflow. 
"buf[NAME_MAX] = value" is invalid since it would access the byte
right after the array.

Also fix the const of modname, do not mess with it to avoid mistakes.

1487a64ffa add kmod_module_get_filtered_blacklist()

returning a new list with remaining modules with the reference
incremented.

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.

The following test was not working and now it is:

$ # go to a dir != mod->dirname
$ cd /lib/modules/$(uname -r)/kernel
$ # try to insert module giving a relative path
$ insmod drivers/acpi/ac.ko

paths are the same. Otherwise fail.

    insert the nodes in the correct order;
