[PATCH 2/5] cache.h: drop active_* macros

[Stefan Beller <sbeller@google.com>]

Based on the coccinelle patch:

@@ @@
-active_cache
+the_index.cache
@@ @@
-active_nr
+the_index.cache_nr
@@ @@
-active_alloc
+the_index.cache_alloc
@@ @@
-active_cache_changed
+the_index.cache_changed
@@ @@
-active_cache_tree
+the_index.cache_tree

Additional manual editing:
* drop the macros from cache.h
* fix the whitespace issue that apply complained about in
  builtin/checkout.c
* builtin/commit.c had an occurrence of active_cache_tree->sha1, which
  was not picked up with the coccinelle patch.
* diff.c and t/t2107-update-index-basic.sh referenced
  active_cache[_changed] in comments, fix them up.
* ative_nr was referenced in comments in read-cache.c and
  builtin/update-index.c, fix them.
