Fix some warnings to allow -Werror
The type used to declare the st_size field of a 'struct stat' can be a 32- or 64-bit sized type, which can vary from one platform to another, or even from one compilation to another. In particular, on linux, if you include the following define: #define _FILE_OFFSET_BITS 64 prior to including certain system header files, then the type used for the st_size field will be __off64_t, otherwise it will be an __off_t. Note that the above define is included at the top of git-compat-util.h. In cache.c, the "%zd" format specifier expects a "signed size_t", another type which can vary, when an __off64_t or a __off_t is provided. To supress the warning, use the PRIuMAX format specifier and cast the st_size field to uintmax_t. This should work an any platform for which git currently compiles. In ui-plain.c, the size parameter of sha1_object_info() and read_sha1_file() is defined to be "unsigned long *" not "size_t *". So, to supress the warning, simply declare size with the correct type.
