quota: description of functions moved to quota.c

Some functions were described both in .h and .c --
duplicates removed from the header.

Some functions were only described in quota.c --
leave it as is.

Some functions were only described in quota.h --
move that description to quota.c

As to the question of where to put those descriptions.
From one side, header is a good place -- you see function
declaration and description. From the other side, it is
often needed to look at the actual code anyway. So IMHO
.c file is a better place for such descriptions.
