lib: Implement i_realloc(mem==NULL) more efficiently
Various parts of code use this to allocate the initial buffer. We can
do this more efficiently by using calloc().

-----------
lib: Use p_malloc() explicitly in first buffer_alloc()
Although there is now code in p_realloc() that it should be just as
efficient, this makes profiling somewhat nicer since it can better
distinguish between actual reallocs and initial allocs.

Log Message:
-----------
lib-index: Use a bit larger initial records buffer size
For example with a mailbox having 160k messages the buffer size is around
10MB. Adding just 1% more space to it allows a lot more appends before the
buffer needs to be realloced. This reduces CPU usage quite a lot.
