alloc.h: move ALLOC_GROW() functions from cache.h
This allows us to replace includes of cache.h with includes of the much smaller alloc.h in many places. It does mean that we also need to add includes of alloc.h in a number of C files. Signed-off-by: Elijah Newren <[email protected]> Signed-off-by: Junio C Hamano <[email protected]>

* Dynamically growing an array using realloc() is error prone and boring.
24+
*
25+
* Define your array with:
26+
*
27+
* - a pointer (`item`) that points at the array, initialized to `NULL`
28+
* (although please name the variable based on its contents, not on its
29+
* type);
30+
*
31+
* - an integer variable (`alloc`) that keeps track of how big the current
32+
* allocation is, initialized to `0`;
33+
*
34+
* - another integer variable (`nr`) to keep track of how many elements the
35+
* array currently has, initialized to `0`.
36+
*
37+
* Then before adding `n`th element to the item, call `ALLOC_GROW(item, n,
38+
* alloc)`. This ensures that the array can hold at least `n` elements by
39+
* calling `realloc(3)` and adjusting `alloc` variable.
40+
*
41+
* ------------
42+
* sometype *item;
43+
* size_t nr;
44+
* size_t alloc
45+
*
46+
* for (i = 0; i < nr; i++)
47+
* if (we like item[i] already)
48+
* return;
49+
*
50+
* // we did not like any existing one, so add one
51+
* ALLOC_GROW(item, nr + 1, alloc);
52+
* item[nr++] = value you like;
53+
* ------------
54+
*
55+
* You are responsible for updating the `nr` variable.
56+
*
57+
* If you need to specify the number of elements to allocate explicitly
58+
* then use the macro `REALLOC_ARRAY(item, alloc)` instead of `ALLOC_GROW`.
59+
*
60+
* Consider using ALLOC_GROW_BY instead of ALLOC_GROW as it has some
61+
* added niceties.
62+
*
63+
* DO NOT USE any expression with side-effect for 'x', 'nr', or 'alloc'.
