Instead of using the often-busted REQUIREDBY entries in the pacman database,
compute them each time they are required. This should help many things:
1. Simplify the codebase
2. Prevent future database corruption
3. Ensure when we do use requiredby, it is always correct
4. Shrink the pmpkg_t memory overhead

It's time to define that alpm_list_add(list, foo) adds 'foo' to the end of
'list' and returns with 'list', because:
1. list is a list, not a set.
2. sortbydeps _needs_ an alpm_list_add definition to work properly.
As a first step, I used this definition in recursedeps.

List head nodes contain null 'prev' pointer, which we can (ab)use to maintain a
back reference to the tail pointer of the list.
While list additions are not _significantly_ improved, they are still sped up.

Linux lstat follows POSIX standards and dereferences a symlink pointing
to a directory if there is a trailing slash. For purposes of libalpm, we
don't want this so make a lstat wrapper that suppresses this behavior.

I broke scriptlet logging with ad691001e2.
Readd more or less what was there before, although it still needs a lot of
work including hopefully rewriting it to a new event subsystem and having
it log to a seperate file.

As seen with the recent upgrade of pacman and the removal of the
pacman.d/current mirrorlist, files that were formerly in the backup array
get deleted upon their removal, which could be dangerous. Instead, we should
use the combined backup array of the old and new package. This fix should
address this issue in a relatively straightforward way.
In addition, old files should be moved to pacsave locations as expected.

My two previous hacks related to this part
(8038190c7c and
b15a5194d1) were caused by the lack of
understanding of a feature introduced a while ago:
Better control over CTRL-C interruptions -- do not leave the DB in an
inconsistent state (54008798ef).
Now I have been looking at this commit, and the added feature is indeed
interesting. The main problem I had with it is that it does a rather
unusual use of alpm_trans_release, which caused a few problems that I tried
to fix in a weird way. I think these problems were caused by the fact that
there weren't any difference between "interrupt transaction" and "release a
transaction which failed" actions from the alpm_trans_release POV. So I
decided to add a new function instead, alpm_trans_interrupt, which is
called on Ctrl+C, and which only sets trans->state to STATE_INTERRUPTED so
that remove_commit and add_commit can exit cleanly at a safe moment. This
allowed me to revert my two previous hacks as well.
Also ensure we handle SIGINT correctly in all cases- if a transaction is
not ongoing, then we can free the transaction and exit quickly.

Suppose a package foo depends on foo1, foo2, ..., foon.
Doing pacman -Rc foo1 foo2 ... foon added foo n times to the removal list,
because what checkdeps return is something like :
foo1 is requiredby foo
foo2 is requiredby foo
...
foon is requiredby foo

This allows us to remove the hack in the frontend where we added a newline
to everything coming out of the pm_printf functions, and instead let the
developer put newlines where they want them. This should be the last hangover
of that auto-newline stuff.

This fixes the failure of the requiredby004 pactest in a not so pretty way,
but it gets the job done. I purposely used the extremely long name of

In 1c9f30b9fa
This change should be done AFTER the TODO in recursedeps is implemented.
Then we'll be able to first sort the list, then call recursedeps which keeps
it sorted. For now, the sorting should still be done as the last step.

Patch from Nagy that makes removedeps use alpm_depcmp.
I also renamed removedeps to recursedeps, as it can have
a more general usage, and added an include_explicit argument,
so we can control if packages explictly installed are added or not.
Note: Small changes made by me (Dan) as well- mostly some English grammar
correction and a few other cleanups.

Currently the d (nodeps) option skips the s (recursive) part,
rendering the Rsd combination totally useless.
This patch makes a recursive removal still possible using the nodeps option,

- Check EACCES in can_remove_file, to verify - we're only checking for a
read-only FS here... if write permissions fail, we can still remove it
- Switched the message when creating DB directories from an error to a debug
message
* Fix the dep tests once and for all (it wasn't working for provides=()
packages)
reordering and adding ones that were forgotten (noticed when trying to
compile after reordering).
* Updated the HACKING file to include information on #include usage.
* print -> vprint in "making dir" function in pactest.
* Moved entirely to alpm_pkg_get_* accessors, to read data on demand
* Mostly removed the INFRQ_ parameters from outside the be_files backend (making
the backend more extensible in the long run)
* packages created from _alpm_db_scan now have the db and origin set (making
accessors actually work for these packages)
* removed _alpm_db_ensure_pkgcache
* totally revamped the _alpm_checkconflicts function, making it cleaner and
easier to read (and thus fix in the long run) - maintainable code ftw
NOTE: feel free to rename the functions... I couldn't think of anything better
* removed an extra loop in sync.c:find_replacements - no sense in looping over
an entire DB while strcmp'ing the name, when we have get_pkgfromcache
Other:
* package struct "license" -> "licenses"
* Created _alpm_sync_find (duplicate code in some places, find_pkginsync
* Minor const correctness changes along the way
* fixed a couple extra '/' pathing issues (non-issues really)
* removed a duplicate pkg_cmp function
* Unified some functions names "package" -> "pkg" for consistency
* Removed the goofy 'faketarget' stuff used for dep testing
* Renamed alpm_pkg_isin -> alpm_pkg_find
* Renamed alpm_db_readpkg -> alpm_db_get_pkg
properly
* Error when re-reading the DB for replacements, wrong info level
* Removed an duplicate debug message "checking for package replacements"
* Check ignorepkg for REAL upgrades...
* Properly check the NOSAVE flag
* some unlink_file (remove.c) cleanup
* fix indent level on handle.c
* Force libalpm paths to end with a '/' char
* Fixed 'target' looping in conflict.c (pmsyncpkg_t, not pmpkg_t)
* Added some debug output to cache and db scanning
** All pactest tests succeed again, yay **
from one package to another seemlessly (knock on wood). This is implemented
through the use of two skip lists in the trans struct- skip_add and
skip_remove, which replace the former trans->skiplist.
* Removed an unnecessary function parameter, added a necessary one.
* If a package has no backup files, print '(none)' under the heading so it is
more obvious.
* Updated my TODO list.
- the code should be clearer, more organized, commented, and have worthwhile
variable names now
- proactive backup=()s now work. That is, adding a file to a backup array
does what it should on the upgrade to that package, no longer forcing you to
wait a full upgrade cycle for it to take effect
* ldconfig was being run twice on an upgrade operation - fixed
* fixed another pm_fprintf/printf output corruption with the progress bars
* refactored some duplicate code for adjusting 'requiredby' lists
* Added config.rpath to .cvsignore
unbelievable amount of strcmp() calls (25 million) due to the list searching.
This has been reimplemented with a set-intersection scheme, due to the fact
that file lists are always ordered. - NEEDS TESTING
* Minor clean up, "globalized" the str_cmp helper to match the alpm comparison
signature, so we can use it elsewhere.
* The --debug params were goofy. New setup allows --debug without params,
--debug=<level> where level 1=debug output, 2=debug and download output,
3=debug, download, and function tracing output. This seems more sane to me.
* Removed PM_LOG_FLOW1 and PM_LOG_FLOW2. They were just confusing. When adding
new functions, it is near impossible to determin if your output should be
"flow1" or "flow2" without tracking all the way up the call chain. Rarely
would one ever say "ok, lets just show "flow2" output. These have both been
replaced with PM_LOG_DEBUG
* Removed the need for the root parameter on alpm_initialize. it is now
defaulted to PM_ROOT just like dbpath and cachedir. This allows alpm to be
initialized BEFORE option parsing in the front end, saving us some duplicate
variables in the frontend.
* Cleaned up front end variables due to early alpm_initialize call.
