libalpm: introduce MALLOC and CALLOC macros
These macros take the place of the common 4 or 5 line blocks of code we had in most places that called malloc or calloc. This should reduce some code duplication and make memory allocation more standard in libalpm. Highlights: * Note that the MALLOC macro actually uses calloc, this is just for safety so that memory is initialized to 0. This can be easily changed in one place. * One malloc call was completely eliminated- it made more sense to do it on the stack. * The use of RET_ERR in public functions (mainly the alpm_*_new functions) was standardized, this makes sense so pm_errno is set.
