VM: new function set_memory_locked(true/false)

it wraps the mprotect/VirtualProtect platform differences and makes it
so you can unify some windows/unix code path forks

VM: removes the template parameter from mark_bits

since mark_bits only deals with arithmetic on memory addresses, it
doesn't need to be specialized so it can be untemplateized

usage in the callback heap instead of the code heap.

VM: Fixup cast formatting after clang-format
...
clang-format doesn't recognize casts to non-pointer/non-template types
so it winds up adding a space between the right paren and the expression
and then failing to recognize prefix operators in the process
(e.g. foo = (cell) & bar; should be foo = (cell)&bar;). This commit
manually fixes up the major cases (fixnum, cell, all types ending in _t).

vm: stage code block map fixup properly for GC
...
Don't update the map until the very last thing, and pass untranslated addresses to the iterator functors. Somewhat complicated by the fact that, for startup_fixup, the map is initialized with fixed-up values, so the fixup functor needs a flag indicating whether it operates with a fixed or unfixed code heap map.

vm: replace assert with FACTOR_ASSERT
...
Factor is finally a real C++ project and has a custom assert macro. Assertion failures were still getting caught as exceptions and causing failure loops. Write our own macro that calls factor::abort on failure.

This makes the separate "code" and "entry_point" fields in word and quotation redundant, so also remove them to reclaim an additional cell per word and quotation object, which should help with #318 .

...
This reverts commit 7d5c8d6990385b94569116a23163d7e75ae21f49. We pretty much can't avoid unwinding frames without some more drastic redesign.

vm: modify-code-heap primitive now takes a pair of parameters, update-existing? and reset-pics?. If no generic words were changed, PICs do not need to be reset. If no existing words were redefined, the code heap doesn't have to be traced at all. Speeds up compilation of PEGs since those create lots of compilation units
