Log message:
*: Move SUBST_STAGE from post-patch to pre-configure

Performing substitutions during post-patch breaks tools such as mkpatches,
making it very difficult to regenerate correct patches after making changes,
and often leading to substituted string replacements being committed.

Log message:
Remove patch that has no effect.

Log message:
Updated minicom to 2.7.1.

New for version 2.7.1:
 - CVE-2017-7467: Fix an out of bounds data access that
   can lead to remote code execution. This issue was found
   by Solar Designer of Openwall during a security audit of
   the Virtuozzo 7 product, which contains derived downstream
   code in its prl-vzvncserver component. The corresponding
   Virtuozzo 7 fix is: \ 
https://src.openvz.org/projects/OVZ/rep … dcf06ca13f

   Openwall would like to thank the Virtuozzo company for
   funding the effort.

Log message:
Drop setuid for bin/minicom, bump PKGREVISION

setuid bin/minicom makes zmodem support with comms/lrzsz unusable.

Log message:
Remove mk/find-prefix.mk usage from the comms category.

The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.

Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure.  Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.

Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.

Log message:
Add SHA512 digests for distfiles for comms category

Existing SHA1 digests verified, all found to be the same on the
machine holding the existing distfiles (morden).  Existing SHA1
digests retained for now as an audit trail.

Log message:
1.22.2
---
- Fix buffering for funny sample formats (namely, 24 bit), that do not
  fit nicely into 32768 bytes. Effect was a nasty endless loop where
  mpg123 needs to be externally killed.

1.22.1
---
- Fix mpg123-id3dump when writing images with funny (manipulated) MIME type.
  Stupid mistake in length computation of the fallback file extension caused
  junk from memory being appended to the filename if the pointer size
  is less than 64 bit. For 64 bit pointers (or longer) it was correct by
  accident.
- Fix pedantic build by cleaning up out123 source, also now really showing
  the encoding list in --longhelp instead of possibly, again, writing junk
  from memory in there.
- Not linking libmpg123 against libltdl anymore (bug 215).
- Update MSVC++ ports a bit to make them work again.

Remove pkgviews: don't set PKG_INSTALLATION_TYPES in Makefiles.
