e07622b56a Cache: implement meat of landlord algorithm and add remove()
allocators: add freelist capability to Bucket; add provision for
variable XOR fixed size allocs
archive: re-tag file buffers if reading uncompressed from archive;
improve LFH fixup logic
file_cache: add cache line invalidation; lock down pages (readonly) when
IO finished
file_io: cleanup+docs; properly cut off at EOF without breaking
alignment.
file_stats: add seek accounting (WIP)
vfs_optimizer: also record file_buf_free in the trace. initial
implementation of archive builder (WIP)
zip: lfh_fixup now more efficient (does not involve buffer manager -
instead it grabs LFH from temp blocks)
tex: plug FileIOBuf leak. avoid writing to tex.hm because that is a
read-only file_buf.

This was SVN commit r3428.

36cbf23c8e v2 of file/res code for thesis:
previous zip.* split up into archive, zip and compression. add O(1)
lookup via memento. add support for writing Zip archive. simplify IO by
having compression module allow queuing input buffers.

file: split up into file, file_Io, file_cache. add atom_fn that enables
string comparison via pointer compare. (stores all filenames/paths in
one place). add statistics gathering.
file_cache: landlord algorithm for caching files as well as LRU block
cache.
file_io: aio code that splits transfers into blocks revamped and made
into class.

vfs: filelist/trace code moved into new vfs_optimizer. add caching logic
to vfs_load.
vfs_optimizer: will generate zip archive (to replace current archive
builder script). not yet done
vfs_tree: major cleanup - now has nice base class rather than union
hackery.

This was SVN commit r3420.

1c1200a049 - massive overhaul of lib error code returning. int -> LibError everywhere.
- add translators from errno and GetLastError to LibError
- clarified return values of callbacks (they must return
INFO_CB_CONTINUE to continue)
- this exposed a few bugs in error handling chains (returning incorrect
values); also reduced say-nothing instances of return -1.
- move CHECK_ERR etc. macros to lib_error

This was SVN commit r3229.

e9864faa97 all resource implementations:
- add automatically called validate function
- make sure dtors correctly handle partial reload failures

all file code: IO routines renamed to io_* from *_io

h_mgr: add suballocator for filenames; some reorganization+cleanup;
better example code and added some notes to docs

snd: reorg to move resource methods next to struct

4aa740bff5 - split up lib/res into file, graphics and sound.
- wposix.cpp: initial support for MEM_RESERVE and MEM_COMMIT semantics
in mmap
- cstr: removed no longer necessary serialization header
- xmlutils: wrap new() calls in nommgr/mmgr; allows tracking other
allocs in this file.
- add u64_from_u32
- various minor comments/improvements.
