compat/pread.c: Add a forward declaration to fix a warning
read_in_full()'s is used in compat/pread.c. read_in_full() is declared in cache.h. But we can't include cache.h because too many macros are defined there. Using read_in_full() without including cache.h is dangerous because we wouldn't recognize if its prototyp changed. gcc issues a warning about that. This commit adds a forward declaration to git-compat-util.h. git-compat-util.h is included by compat/pread.c _and_ cache.h. Hence, changes in cache.h would be detected.
