Log message:
chat/libotr, chat/irssi: Pass through libgcrypt-config on cross.

This is kludgey, on two levels:

1. We are relying on the _cross-built_ libgcrypt-config to be a shell
   script that can be executed at build-time.  (Why can't we just use
   pkg-config?  Downstream packages' configure scripts have to be
   patched to be taught to do this -- the libgcrypt.m4 autoconf library
   that gcrypt ships with doesn't know how.)

2. Knowing where the libgcrypt-config lives should be defined in one
   place, security/gcrypt/buildlink3.mk, not in every user like
   textproc/libxml2, chat/libotr, chat/irssi, &c.

But this will get irssi cross-building, at least.

No change to native build because conditional on USE_CROSS_COMPILE.

Log message:
Update to 4.1.1.

This is a security release addressing CVE-2016-2851.

- Fix an integer overflow bug that can cause a heap buffer overflow (and
  from there remote code execution) on 64-bit platforms
- Fix possible free() of an uninitialized pointer
- Be stricter about parsing v3 fragments
- Add a testsuite ("make check" to run it), but only on Linux for now,
  since it uses Linux-specific features such as epoll
- Fix a memory leak when reading a malformed instance tag file
- Protocol documentation clarifications

Log message:
Add SHA512 digests for distfiles for chat category

Problems found with existing distfiles:
	distfiles/icb-5.0.9.tar.gz
	distfiles/icb.2.1.4.tar.Z
	distfiles/zenicb-19981202.tar.gz
No changes made to these /distinfo files.

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

Log message:
