Denys Vlasenko 2fb4db3e7a Optimization: eliminate all remaining usages of strcat() 
After this change, we don't use strcat() anywhere.

* defs.h: Change sprinttv() return type to char *.
* time.c (sprinttv): Return pointer past last stored char.
* desc.c (decode_select): Change printing logic in order to eliminate
usage of strcat() - use stpcpy(), *outptr++ = ch, sprintf() instead.
Also reduce usage of strlen().
* stream.c (decode_poll): Likewise.
