Denys Vlasenko a1d541ec56 Eliminate code duplication in time printing, reduce a few static buffers 
text	   data	    bss	    dec	    hex	filename
 238454	    664	  28772	 267890	  41672	strace.before
 238106	    664	  28676	 267446	  414b6	strace

* defs.h: Add TIMESPEC_TEXT_BUFSIZE and TIMEVAL_TEXT_BUFSIZE defines.
Add 'int special' parameter to sprinttv().
* time.c (sprinttv): Add 'int special' parameter, and use it
similarly to 'int special' parameter of printtv_bitness().
(printtv_bitness): Use sprinttv() instead of duplicating its code.
(print_timespec): Use sprint_timespec() instead of duplicating
its code.
* desc.c (decode_select): Use TIMEVAL_TEXT_BUFSIZE instead of 128
when checking remaining buffer size.
* net.c (sys_recvmsg): Use TIMESPEC_TEXT_BUFSIZE instead of 128
for static buffer size.
* stream.c (decode_poll): Use TIMESPEC_TEXT_BUFSIZE instead of 128
when checking remaining buffer size.
