library: relocate the typedef used in alloc.h override There is no longer justification for placing a typedef employed in overriding that alloc.h message handler in the procps.h header file. So this commit just moves it to the alloc.h header file itself where's it's needed! [ gosh, sure wish i had thought to relocate this guy ] [ when the changes in the 1st commit shown were made ] Reference(s): . most recent related changes commit 18e5aecd2b61387ebd82c83f6f716e4c8e093272 . place where it should have been relocated commit 2865ded64e72e0bec721dad9b442dab0899ee2b0 Signed-off-by: Jim Warner <james.warner@comcast.net> 2017-12-16 11:30:00 +05:30			`typedef void (message_fn)(const char __restrict, ...) __attribute__((format(printf,1,2)));`

library: expanded/generalized memory allocation provisions A callback provision in the form of xalloc_err_handler (of type message_fn) was added to the alloc module. This change allowed a program like top, who alters the termios structure, to override the default fprint(stderr...) behavior in the event of an error. The new function xstrdup was also added for symmetry. 2011-11-16 22:19:02 +05:30			`/* change xalloc_err_handler to override the default fprintf(stderr... */`

pmap: use correct types for memory allocation Fixes error which did not happen always. Changes of being affected by the bug where greater the more there where pids defined as pmap argument. The debian bug referral can almost certainly reproduce the problem, especially when tried multiple times in row. pmap: malloc.c:3096: sYSMALLOc: Assertion `(old_top == (((mbinptr) (((char ) &((av)->bins[((1) - 1) 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) && old_size == 0) \|\| ((unsigned long) (old_size) >= (unsigned long)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t))) - 1))) && ((old_top)->size & 0x1) && ((unsigned long)old_end & pagemask) == 0)' failed.
