Version bump as preparation for Asterisk update.
In other news:
- upgrades ULRs to https
- adds new configure switch --disable-darwin-ssl (doesn't apply to
OpenWrt, but disable it explicitly anyway)
- use INSTALL_DATA for pkg-config file
- patch naming changed to be in line with Asterisk's patch naming,
making maintenance easier
- drops some patches, adds some new ones from Asterisk (mainly reverts
of some pjproject commits which turned out to cause memory leaks)
