Ondřej Surý c3250a9b81 Use assertions to check for failed allocations
It was discovered that named could crash due to a segmentation fault
when jemalloc was in use and memory allocation failed.  This was not
intended to happen as jemalloc's "xmalloc" option was set to "true" in
the "malloc_conf" configuration variable.  However, that variable was
only set after jemalloc was already done with parsing it, which
effectively caused setting that variable to have no effect.

While investigating this issue, it was also discovered that enabling the
"xmalloc" option makes jemalloc use a slow processing path, decreasing
its performance by about 25%. [1]

Additionally, further testing (carried out after fixing the way
"malloc_conf" was set) revealed that the non-default configuration
options do not have any measurable effect on either authoritative or
recursive DNS server performance.

Replace code setting various jemalloc options to non-default values with
assertion checks of mallocx()/rallocx() return values.
