parsers.c: remove warning: 'size' may be used uninitialized in this function...

parsers.c: remove warning: 'size' may be used uninitialized in this function Some compilers / compiler options (such as gcc 4.7) would emit warnings: mercurial/parsers.c: In function 'pack_dirstate': mercurial/parsers.c:306:18: warning: 'size' may be used uninitialized in this function [-Wmaybe-uninitialized] mercurial/parsers.c:306:12: warning: 'mode' may be used uninitialized in this function [-Wmaybe-uninitialized] It is apparently not smart enough to figure out how the 'err' arithmetics makes sure that it can't happen. 'err' is now replaced with simple checks and goto. That might also help the optimizer when it is inlining getintat().
