malloc: checked_request2size failure deadlocks
For some rarely cases(almost App bugs), calling malloc with a very largre size, checked_request2size check will fail,set ENOMEM, and return 0 to caller.
But this will let __malloc_lock futex locked and owned by the caller. In multithread circumstance, other thread calling malloc/calloc will NOT succeed and get locked.

resolv: fix unaligned tmp buffer corner-case
On execution of "inet/gethost_r-align" test I noticed failure due to unaligned access (instaed of 4-byte aligned 1-byte aligned address was attempted to be accessed).
Further investigation confirmed this nice and helpful test failure. Following commit removed usage of ALIGN_BUFFER_OFFSET on entry to __read_etc_hosts_r(): http://git.uclibc.org/uClibc/commit/?id=f65e66078b9f4d2d7f0fc336dee36e78fc46...
So indeed if target architecture doesn't allow unaligned access and provided tmp buffer is not word aligned (and we will deal with pointers which means word-sized data units), then CPU will fail during execution.
In case of ARC we'll see "Unaligned access" exception like this: --->8--- # potentially unexpected fatal signal 7. Path: /root/uClibc/test/inet/gethost_r-align CPU: 0 PID: 5514 Comm: gethost_r-align Not tainted 3.13.11 #2 task: 8f42a580 ti: 8f40e000 task.ti: 8f40e000

To fix this problem we'll re-introduce tmp buffer force alignment before config parser invocation.
