Added e-mail to MAINTAINER field
[telephony/baresip] get rid of "re_mk" package and a bunch of patches

* Now "telephony/baresip/Makefile.inc" provides all configuration options
  "re_mk" was supposed to set up.
* Use user settings whenever possible.
* Hopefully baresip now builds on static architectures. (Didn't check.)
