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.
