If a package has an mtree file, using pacman -Qkk will read that
file and use it to perform more in depth package checking.
Currently this only checks for file presence.

There is going to be a lot of overlap in the code for the quick
and full checks that can be abstracted into their own functions.
Also many other file checking functions will be needed for the
full check. Put all these in a separate source file.

I find that when copying the output of "pacman -Qs foo" into a
"pacman -Qi" operation to get more information on the packages, I
consistently copy the "local/" prefix. It is a minor usability
improvement to strip this if present.

Check for an exact match when querying ownership of files in the root.
Previously, our test was too simple and would match the the basename of
package files against the query parameter, e.g.
$ pacman -Qo config
/config is owned by cower-git 20120614-1
Adds a new test to verify this behavior, query007.py.

This dramatically improves upon a much older attempt in 2008 in commit
ce3d70aa99. We don't need to call it once per line we print unless
there is a reasonable expectation of being able to resize the terminal
mid-operation; this is really only the case during our callback progress
bars.
Some before and after numbers of ioctl() calls, gleaned from strace of
the following operations (no targets to any of them to maximize the
amount of output):
pacman -Qii : 37768 -> 2616 (93.1% decrease)
pacman -Qs : 2616 -> 4 (99.8%)
pacman -Sii : 133036 -> 10926 (91.8%)
pacman -Ss : 10926 -> 14 (99.9%)
Obviously the search results are astounding; we only call getcols()
once in the case of -Qs, and once per repo in the case of -Ss. For
-Qii and -Sii we are still calling it once per package, but this is
much better than once per line of info output.

This makes several small adjustments to our exposed method names, and in
one case, parameters. The justification here is to make methods less odd
in their naming convention. If a method takes an alpm_db_t argument, the
method should be named 'alpm_db_*', but perhaps more importantly, if it
doesn't take a database as the first parameter, it should not.
Summary of changes:
alpm_db_register_sync -> alpm_register_syncdb
alpm_db_unregister_all -> alpm_unregister_all_syncdbs
alpm_option_get_localdb -> aplpm_get_localdb
alpm_option_get_syncdbs -> aplpm_get_syncdbs
alpm_db_readgroup -> alpm_db_get_group
alpm_db_set_pkgreason -> alpm_pkg_set_reason
All methods keep the same argument list except for alpm_pkg_set_reason;
there we drop the 'handle' argument as it can be retrieved from the
passed in package object.

Ensures that config.h is always ordered correctly (first) in the
includes. Also means that new source files get this for free without
having to remember to add it.
We opt for -imacros over -include as its more portable, and the
added constraint by -imacros doesn't bother us for config.h.
This also touches the HACKING file to remove the explicit mention of

Now that pm_printf() always prints to stderr, we don't need this second
function that was always used with stderr as the first argument. Thus,
this patch removes the function and makes the following sed replacement:

This replaces several printf calls of the following styles:
printf("%s", ...);
printf("some fixed string");
printf("x");
We can use either fputs() or putchar() here to do the same thing
without incurring the overhead of the printf format parser.
The biggest gain here comes when we are calling the print function in a
loop repeatedly; notably when printing local package files.
$ /usr/bin/time ./pacman-before -Ql | md5sum
0.25user 0.04system 0:00.30elapsed 98%CPU

This accomplishes quite a few things with one rather invasive change.
1. Iteration is much more performant, due to a reduction in pointer
chasing and linear item access.
2. Data structures are smaller- we no longer have the overhead of the
linked list as the file struts are now laid out consecutively in
memory.
3. Memory allocation has been massively reworked. Before, we would
allocate three different pieces of memory per file item- the list
struct, the file struct, and the copied filename. What this resulted
in was massive fragmentation of memory when loading filelists since
the memory allocator had to leave holes all over the place. The new
situation here now removes the need for any list item allocation;
allocates the file structs in contiguous memory (and reallocs as
necessary), leaving only the strings as individually allocated. Tests
using valgrind (massif) show some pretty significant memory
reductions on the worst case `pacman -Ql > /dev/null` (366387 files
on my machine):
Before:
Peak heap: 54,416,024 B
Useful heap: 36,840,692 B
Extra heap: 17,575,332 B
After:
Peak heap: 38,004,352 B
Useful heap: 28,101,347 B
Extra heap: 9,903,005 B
Several small helper methods have been introduced, including a list to
array conversion helper as well as a filelist merge sort that works
directly on arrays.

The supposed safety blanket of this function is better handled by
explicit length checking and usages of strlen() on known NULL-terminated
strings rather than hoping things fit in a buffer. We also have no need
to fully fill a PATH_MAX length variable with NULLs every time as long
as a single terminating byte is there. Remove usages of it by using
strcpy() or memcpy() as appropriate, after doing length checks via
strlen().

They are placeholders, but important for things like trying to re-sync a
database missing a signature. By using the alpm_db_validity() method at
the right time, a client can take the appropriate action with these
invalid databases as necessary.
In pacman's case, we disallow just about anything that involves looking
at a sync database outside of an '-Sy' operation (although we do check
the validity immediately after). A few operations are still permitted-
'-Q' ops that don't touch sync databases as well as '-R'.

This gives us more granularity than the former Never/Optional/Always
trifecta. The frontend still uses these values temporarily but that will
be changed in a future patch.
* Use 'siglevel' consistenly in method names, 'level' as variable name
* The level becomes an enum bitmask value for flexibility
* Signature check methods now return a array of status codes rather than
a simple integer success/failure value. This allows callers to
determine whether things such as an unknown signature are valid.
* Specific signature error codes mostly disappear in favor of the above
returned status code; pm_errno is now set only to PKG_INVALID_SIG or
DB_INVALID_SIG as appropriate.

Both md5sum verification and PGP verification can and should be done at
package load time. This allows verification to happen as early as
possible for packages provided by filename and loaded in the frontend,

packages later down the road.

The various "level" values were a bit crazy to decipher, and we were
doing some very interesting comparisons in certain places. Break it out
into two parameters instead so we can seperate the type from the extra
information display, and do things accordingly.
Nothing changes with the display of any of the five types we currently
show: -Si, -Sii, -Qi, -Qii, -Qip.
Something to note- we should expose the PKG_FROM enum type somehow, this
patch leaves the door open to do that quite easily.
