ports-mgmt/pkg-devel: 2.1.99.5

pkg changes:

• really use the cache file
• improve error message when failing at parsing manifest printing the path of the manifest.
• improve multi repo priosation handling
• fix selection of the most recent package in multirepo mode
• fix the scheduler over splitting the upgrades

Note this version will become 2.2.0 if all tests are ok

port changes:
remove the debug cflags by default, if needed people can always rebuild
with them and it gives the false impression of performances issues vs
release.
