Refactor plist parsing a bit to make it easier for regression testing

Add test cases for pkg_add_dir_to_del

Add a test case for parse_mode

Fix pkg_validations tests

Merge remote-tracking branch 'origin/pr/957'

Convert over to Kyua

Merge branch 'master' into gsoc

Update tests to cover new %Od and %OD format codes.

Fix test compilation

Fix building tests with gcc48

Use ATF_REQUIRE directly instead of ATF_REQUIRE_EQ to validate != NULL

Also test PKG_FILE and PKG_REMOTE

Add complete tests to validate a PKG_INSTALLED package

Add test case for pkg_is_valid

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 tests for new pkg_printf() formats: %R, %V, %u

Add tests for %q -- package architecture

force the symlink creation to avoid the build the fail if pkg_printf.c already exist

Add tests for %S

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

Update tests due to adding %e, %dk and %rk

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

Use a lest cryptic name for the tests

Still rearranging the test programs

Begin merging pkg_printf tests into new testing framework

Make the compiled test programs dynamically link against libpkg.so.1 in the build tree, rather than any copy that happens to be on the usual library search path.

Fix the path to the libpkg dir -- if it's not right, we won't test against what was just compiled, but what was last installed.

bsd.tests.mk -- allow compiling multiple tests per directory.

Update to add keys argument to pkg_parse_manifest() which implies adding calls topkg_manifest_keys_{new,free}().

Add Atffile for lib

Import bsd.prog.mk as the basis for bas.tests.mk

Add more pkg field tests

Rename pkg_value -> pkg_str

Enable pkg field tests

Prepare layout for atf-sh
