Fix packing +UPGRADE scripts

Remove dead code

Merge branch 'pkg_printf'

Actually, change %N to produce the repo identity -- the tag that is used in pkg.conf(5) -- rather than repo name: the basename of the sqlite file and the name the database is mounted as (which is properly of interest only to the inernals of pkg, and not what we want pkg query etc. to display).

Add new %N pkg_printf() escape: Repository name, plus doccumentation and testing for the same.

Add three new pkg_printf() formats:

Add a %q format -- package architecture

pkg repo only create the database in 2001 (aka 1.0) format

Refactor the signing repository code so that the key is being asked only once

Add %S as a new format code to print arbitrary character strings.

Nuke PKG_INFOS from orbit (it's the only way to be sure.)

Be explicit about why a port is being reinstalled

Reformat the fmt[] array

Add %e -- package description

Move alloc() / free() of struct percent_esc * up a level in the function call tree -- reduce the number of alloc()/free() cycles.

Initialise struct pkg_foo *foo properly so that the pkg_foo iterator works correctly.

Add support for %A -- Annotations -- to pkg_printf

Fix pkg_printf to work with shlibs required/provided

Reorder pp_fmt_t so that multi-character codes come before single characters. This allows multi-character codes to be used at the top level, and not just in format trailers.

Rework the %-esc parsing as a consequence of shortcomings exposed by work on testing

Create a liclog_val() output function (maintaining the same layering as for other output types) even though there's only one place it would get called from.

Implement tests of human_number()

Add a new sub-dir under tests for pkg_printf. This pokes around in the private internals of pkg_printf, so it specially compiles pkg_printf.c using CPP trickery to make all the static functions in there extern. This means it has to be a separate binary from the tests in ../lib

Split out the typedefs and function prototypes into a new private/pkg_printf.h header. This is to support linking against a test program so that testing can exercise the pkg_printf internals.

Fix registering shlibs with a stage directory

Repo names vs. identifiers

Add a new member reponame to struct pkg_repo

Remove dead code

Add per repo mirror type, and use the repo all over the place

Fix build after addition of -Wmissing-variable-declarations to WARNS=6 in HEAD

Do not alter a struct pkg to set the new version, but only push the old informations on it

Load repositories from ${PREFIX}/etc/pkg/repos/

Remove dead code

Cleanup job_pattern to get only one pattern per entry

pkgdb_query_fetch has already been removed

switch pkg delete to new world order

Convering pkg upgrade to new solver

Refactor pkg install with a cleaner solver.

Do not use sqlite anymore to compute the autoremove

Add compact manifest to a package.

Introduce flags for manifest emitting.

Add flags to pkg_open to allow some optimizations.

Insert sufficient spaces to make the SQL parse.

Add compatibility VIEW and TRIGGERS so pkg-1.0 or applications linked against libpkg(3) from pkg-1.0 can use a database created by pkg-1.1 or greater.

Add ability to parse manifest directly from a struct archive

Remove dead code

Uses has to figure out manifest keys.

Generally change annotation key -> tag

Add pkg_delannotation()

Calling it 'abstract metadata' doesn't really do it for me. Change to 'annotation' everywhere, because that's a much better description.
