  Bugs, Installed-Size, MD5sum, Origin, Original-Maintainer, SHA1, SHA256,
  Task.
- pkg.h (enum relop): added comments showing the respective symbol
- pkg.h (enum relop): added rel_gg (>>), rel_le (<=), and rel_ll (<<)

9d208dd855 qpkg: added parsing and recording of Provides data
- pkg.h (enum flags): new flags QPKG_PROVIDED to indicate that the
  package is only a provision, not an installable package
- fixup.h, fixup.c (complete_provisions): search for provisions that do
  not have a real package associated with them, create a package for
  them, and mark it as QPKG_PROVIDED
- qpkg.c (do_fixups): invoke complete_provisions
- pkg.h (struct pkg): add list of (virtual or real) packages a given
  package provides
- pkg.c (new_pkg): initialize pkg->provides
- pkg.c (free_pkg): deallocate pkg->provides
- gobble.c (gobble_buf): parse the list of packages a package provides
- TODO: updated status of Provides support

bbf9c42bc8 qpkg: move "struct pkg" and its allocation from gobble.c and qpkg.h to pkg.[hc]
- Makefile (OBJS_qpkg): added pkg.o
- gobble.c (gobble_buf): moved "struct pkg" allocation to function new_pkg
  in pkg.c
- qpkg.h: moved "struct pkg" and subordinate structures to pkg.h
- pkg.h, pkg.c (new_pkg, free_pkg): provide package structure definition,
  allocation, and deallocation
- fixup.c, gobble.c, prereq.c, qpkg.c: include "pkg.h"
- gobble.c (finish_pkg): use free_pkg instead of just "free" to avoid
  leaking memory

6c66fa6053 qpkg: store dependencies and conflicts in file order
- gobble.c (gobble_buf): list_with_version reversed the order of the list
  items. It makes the behaviour of later algorithms more intuitive if we
  maintain the file order.

83c716424f qpkg: perform sanity checks after parsing a package entry
- gobble.c (compact_pkg, gobble_buf): renamed compact_pkg to finish_pkg
- gobble.c (finish_pkg): check that the package has a version
- gobble.c (finish_pkg): check that the package has an architecture
- gobble.c (finish_pkg): check that the package either has a file name or
  is installed

f14c041e51 qpkg: record Architecture: tag
- qpkg.h (struct pkg): added "arch" field for the architecture
- gobble.c (gobble_buf): record the architecture
- gobble.c (gobble_buf): fail if trying to set the file name twice
- qpkg.c (main): initialize trees before doing anything else, so that the
  argument processing stays together

44e4434b4c qpkg: towards "struct id" without jrb reference - change ID creation
- id.h, id.c (make_id): return a "struct jrb *", so that we have access to
  key and value
- gobble.c (ID, gobble_buf): adapt to above change
- gobble.c (compact_pkg, gobble_buf): keep the RB node reference instead
  of awkwardly regenerating it via pkg->id->jrb

a63823e26a qpkg: turn pkg->installed into pkg->flags, allowing for future expansion
- qpkg.h (enum flags, struct pkg): replaced "installed" with "flags", one
  of them being QPKG_INSTALLED
- gobble.c (compact_pkg, gobble_buf), prereq.c (push, resolve): adapted
  for above change

3d1ef02aba qpkg: added copyright headers and changed name to emphasize speediness
- Makefile, gobble.h, gobble.c, id.h, id.c, prereq.h, prereq.c, qpkg.h,
  qpkg.c, rbtest.c: added copyright header
- id.c: include jrb.h (for completeness)
- README: change name from "Query package databases" to "Quick package
  database query"

9481934c9a qpkg: Makefile cleanup and added OpenWRT target
- Makefile: added automatic dependenceies (needs SHELL = /bin/bash)
- Makefile: added non-verbose builds
- Makefile (jlime): set CC_normal instead of CC, so that also cross-builds
  can be non-verbose
- Makefile (openwrt): new target to cross-compile for OpenWRT with uClibc
- Makefile (spotless): added "spotless" target
- gobble.c: uClibc may not have posix_madvise, so replace it with a dummy
  if building for uClibc

ed0281f306 qpkg/gobble.c (EXPECT): added variant that just skips over expected text
If the package database is sane, then we don't need to check that all
the field names match what we expect. This saves a few more CPU cycles.
However, if anything goes wrong, the consequences may be unpleasant.
Thus, we default to the slow but safe approach.

64c70e77f4 qpkg: use "val" field of jrb nodes instead of keeping one in "struct id"
- id.h (struct id), id.c (make_id): remove field "value"
- gobble.c (compact_pkg, gobble_buf), prereq.c (list_all_packages,
  list_one_package, find_prereq): use id->jrb->val instead of id->value

9b5480ab3e qpkg: merge identical versions in package databases
This avoids turning a prerequisite search into a massacre of, guessed,
O(sqrt(2^requisites)).

- gobble.c (gobble_buf, compact_pkg): if a package being added has the same
  version as an existing package with the same name, merge them and keep
  only one

0ca4751b77 qpkg: some cleanup, prerequisite search speedup
With the reduction of search depth, "prereq abiword" takes about 3 minutes
on my PC. (Obviously, this can still be improved.)

- gobble.c (gobble_buf): if pkg->id->value is NULL, just it as such
- prereq.c (push): abort if trying to consider a package already considered
  or installed
- prereq.c (conflicts): before being satisfied with using an installed
  package, make sure it really satisfies the requirement
- prereq.c (conflicts): abort if an installed package conflicts
- prereq.c (conflicts): added some debugging output (temporary)
- prereq.c (conflicts): cut the search if we can't do better than a
  previous match
