Prevent an implicit int promotion in malloc/tst-alloc_buffer.c

According to ISO C11, section 6.5.3.3 "Unary arithmetic operators", the
result of the ~ operator is the bitwise complement of its (promoted)
operand.
This can lead to a comparison of a char with another integer type.

Tested on powerpc, powerpc64 and powerpc64le.

	* malloc/tst-alloc_buffer.c (test_misaligned): Cast to char
	before comparing with another char.

Implement allocation buffers for internal use

This commit adds fixed-size allocation buffers.  The primary use
case is in NSS modules, where dynamically sized data is stored
in a fixed-size buffer provided by the caller.

Other uses include a replacement of mempcpy cascades (which is
safer due to the size checking inherent to allocation buffers).
