string-buffer: Remove INT_MAX limitation.

Browse Source 
* lib/string-buffer.h (sb_appendvf, sb_appendf): Document that errno is
set upon failure.
* lib/string-buffer-printf.c: Include <errno.h>.
(sb_appendvf): Call vsnzprintf instead of vsnprintf. Ensure errno is
set upon failure.
(sb_appendf): Likewise.
* modules/string-buffer (Depends-on): Add vsnzprintf-posix. Remove
vsnprintf-posix.
* tests/test-string-buffer.c (main): Test error code from sb_appendf.
