b3d10d7bf1 Introduce dm_strncpy
Should be faster then strncpy - since we could avoid clearing 4KB pages
with each strncpy(...,PATH_MAX).
Also it's easy to check whether string fit - and eventually avoid
to continue working we incomplete string.

f72b184e3e Limit number of mem allocs and copies
If we have good enough glibc to return number of needed chars, do not
loop try to reach good size, but use this size directly for allocation,
saving also last strdup.

Since now we start with 16 bytes - skip buffer realloc for shorter string.

36ddbdbbe2 Return error for failing allocation
Fix case, where final strdup would have failed and it would miss to return
failure for this case and return success and NULL pointer.

6fe315d412 Fix memory overwrite
Transfer of build_dm_uuid() function into libdm made uuid_prefix as parameter,
thus sizeof() was replaced with strlen() and room for '\0' missed.

As it's only fix in current version - no whatsnew.

e59e2f7c3c Move the core of the lib/config/config.c functionality into libdevmapper,
leaving behind the LVM-specific parts of the code (convenience wrappers that
handle `struct device` and `struct cmd_context`, basically). A number of
functions have been renamed (in addition to getting a dm_ prefix) -- namely,
all of the config interface now has a dm_config_ prefix.

Remove unneeded ';'
