Wilco Dijkstra ac92c66821 Fix tcache count maximum (BZ #24531) 
The tcache counts[] array is a char, which has a very small range and thus
may overflow.  When setting tcache_count tunable, there is no overflow check.
However the tunable must not be larger than the maximum value of the tcache
counts[] array, otherwise it can overflow when filling the tcache.

	[BZ #24531]
	* malloc/malloc.c (MAX_TCACHE_COUNT): New define.
	(do_set_tcache_count): Only update if count is small enough.
	* manual/tunables.texi (glibc.malloc.tcache_count): Document max value.

(cherry picked from commit 5ad533e8e6)
