Edwin Török a91d1616d8 libs/call: cache up to 4 pages in hypercall bounce buffers ...

During migration there are a lot of mmap/munmap calls,
because xc_get_pfn_type_batch() exceeds the default hypercall bounce
buffer cache size, and needs to allocate every time it is called.

munmap() is slow, especially in a PV Dom0 (takes an emulation fault),
so is best avoided.

Eventually it'd be good if the memory pool from  xmalloc_tlsf.c
was reused here, but for now make it handle the commonly encountered
sizes (so far up to 4 pages).
