Avoid #'delq in core code, for the sake of style and a (very
slightly) smaller binary.

1. Replace (delq nil (mapcar ....)) with analogous (mapcan ...)
forms; this is in non-dumped files, it was done previously in
dumped files.
2. Replace (delq FOO (copy-sequence BAR)) with (remove* FOO BAR),
where #'eq and #'eql are equivalent
3. Replace (delq FOO BAR) with (delete* FOO BAR), where FOO is not
a non-fixnum number. Saves a little space in the dumped file
(since the compiler macro adds :test #'eq to the delete* call if
it's not clear that FOO is not a non-fixnum number).

| 30 A "block-type object" is used to efficiently allocate and free blocks | |
| 31 of a particular size. Freed blocks are remembered in a free list and | |
| 32 are reused as necessary to allocate new blocks, so as to avoid as | |
| 33 much as possible making calls to malloc() and free(). | |
| 34 | |
| 35 This is a container object. Declare a block-type object of a specific type | |
| 36 as follows: | |
| 37 | |
| 38 struct mytype_blocktype { | |
| 39 Blocktype_declare (mytype); | |
| 40 }; | |
| 41 | |
| 42 Use the following functions/macros: | |
| 43 | |
| 44 structype *Blocktype_new(structype) | |
| 45 [MACRO] Create a new block-type object of the specified type. | |
| 46 The argument to this call should be the type of object to be | |
| 47 created, e.g. foobar_blocktype. | |
| 48 type *Blocktype_alloc(b) | |
| 49 [MACRO] Allocate a block of the proper type for the specified | |
| 50 block-type object and return a pointer to it. | |
| 51 Blocktype_free(b, block) | |
| 52 Free a block of the type corresponding to the specified block-type | |
| 53 object. | |
| 54 Blocktype_delete(b) | |
| 55 Destroy a block-type object and the memory allocated to it. | |
