core: Add thread-safe group info functions with dynamic buffers
...
Provides getgrgid, getgrnam, getpwuid & getpwnam replacements that are
thread safe (a la getgrgid_r() and friends) that internally
handle allocating big-enough buffers to avoid ERANGE errors
on large users or groups.

object: speed up type verification by not relying on strcmp()
...
Instead of using string contents for type identification use the address
of a constant string array. This should speed up type verifications a
little sind we only need to compare one machine word instead of a full
string. Also, this saves a few strings.
To make clear that types must be compared via address and not string
contents 'type_name' is now called 'type_id'.
This also simplifies the macros for declaring and defining public and
private subclasses.

equivalent C implementation. Note that most of these functions are deprecated in
liboil and that none of them had any optimisations. We can further specialize
our handrolled versions for some extra speedups.
