Slab: simplified allocation from slots.
...
Removed code that would cause an endless loop, and removed condition
check that is always false. The first page in the slot list is
guaranteed to satisfy an allocation.

Slab: fixed the number of pages calculation.
...
When estimating the number of pages, do not count memory for slots.
In some cases this gives one extra usable memory page.

free range was not detected.

Core: added ngx_slab_calloc() and ngx_slab_calloc_locked().
...
These functions return zeroed memory, analogous to ngx_pcalloc().

Core: slab allocator free pages defragmentation.
...
Large allocations from a slab pool result in free page blocks being fragmented,
eventually leading to a situation when no further allocation larger than a page
size are possible from the pool. While this isn't a problem for nginx itself,
it is known to be bad for various 3rd party modules. Fix is to merge adjacent
blocks of free pages in the ngx_slab_free_pages() function.

Core: slab log_nomem flag.
...
The flag allows to suppress "ngx_slab_alloc() failed: no memory" messages
from a slab allocator, e.g., if an LRU expiration is used by a consumer
and allocation failures aren't fatal.
The flag is now used in the SSL session cache code, and in the limit_req
module.

Handling of ngx_int_t != intptr_t case.
...
Casts between pointers and integers produce warnings on size mismatch. To
silence them, cast to (u)intptr_t should be used. Prevoiusly, casts to
ngx_(u)int_t were used in some cases, and several ngx_int_t expressions had
no casts.
As of now it's mostly style as ngx_int_t is defined as intptr_t.
