gvalue: Add explicitly signed g_value_get_schar() and g_value_set_schar()

Browse Source 
The documentation for G_TYPE_CHAR says:

"The type designated by G_TYPE_CHAR is unconditionally an 8-bit signed
 integer."

However the return value for g_value_get_char() was just "char" which
in C has an unspecified signedness; on e.g. x86 it's signed (which
matches the GType), but on e.g. PowerPC or ARM, it's not.

We can't break the old API, so we need to suck it up and add new API.
Port most internal users, but keep some tests of the old API too.
