Update sysutils/entr to entr-3.7

== 3.7: February 27, 2017

Log message:
Set MANPREFIX consistently for all OPSYSs (otherwise users of
Makefile.{linux,macos} MAKE_FILEs will set their MANPREFIX differently to the
one defined in Makefile.bsd)

No functional changes intended for Makefile.bsd MAKE_FILE OPSYSs
(and so no PKGREVISION bump).

Log message:
Update sysutils/entr to 3.4.

pkgsrc changes:
 - Add a LICENSE (isc, but there are also some third parties code used by entr
   that are under a 2-clause-bsd)
 - Do not disturb the provided configure script (that just copy the
   Makefile.platform to Makefile) and just include the proper MAKE_FILE
   depending on OPSYS. (thanks to jperkin@ and tnn@ for misc suggestions)
   This will hopefully fix build problems for operating systems where entr
   previously failed to build.
 - Add a TEST_TARGET in order to run the unit test provided
 - Delete patches/patch-Makefile.bsd, imported upstream

== 3.4: December 12, 2015
 - Terminate the child process before exiting when the reload option is combined
   with the directory watch option
 - Direct users to http://entrproject.org/limits.html if the maximum number of
   open files is exceeded

== 3.3: October 23, 2015
 - Substitute '/_' only with regular files when using the directory watch option
 - Bugfix when tracking the first file to change
 - Display release number along with usage

== 3.2: April 9, 2015
 - Execute the utility immediately after registering watch events. Old behavior
   is restored using new postpone option ('-p')
 - Relocated 'reload-browser' to http://entrproject.org/scripts/reload-browser
 - Drop FIFO support to further simply code and documentation. FIFO mode was
   conceptually good, but EXEC mode is intelligent hand easily handles the vast
   majority of use cases.
 - Remove kFreeBSD as a target platform

== 3.1: March 4, 2015
 - Return error code indicating exit reason after handling signals
 - Restart mode sets process group to ensure that wrapper scripts do not prevent
   signals from reaching child processes
 - Removed DEBUG printf statements

== 3.0: December 19, 2014
 - Man page highlights the flexibility of executing a commands using a shell
 - 'reload-browser', a cross-platform script for reloading the current tab in
   one or more browsers
 - system_test.sh auto-upgrades to bash if the default shell does not support
   the ERR trap
 - Workaround implemented for Linux using fstat(2) to detect if a binary was
   removed if inotify issues IN_ATTRIB but not IN_DELETE_SELF
 - Use calloc(3) to take advantage of overflow detection

== 2.9: June 10, 2014
 - RPM package by @funollet
 - Moved alternate Makefiles to contrib/
 - Trigger actions when a file is truncated on BSD
 - Improved format of DEBUG messages
 - Added missing extern for missing/fmemopen.c to avoid warning on MacOS 10.7+
 - No longer register NOTE_EXTEND; this event is not always merged with
 - New directory-watch option ('-d'). In this mode a shell while-loop can be
   used to track the addition of new files.

== 2.8: March 15, 2014
 - Iteratively check for new file system events using a 1ms timeout after a file
   has been renamed or removed in order to prevent the utility from being
   executed before successive changes from a version control system have
 - Regression tests are now system tests that depend on and use Vim and
 - Timing on regression tests has been tightened to only support real hardware;
   they are not expected to pass in emulated environments.
 - More correctly identify the first file to trigger a file change notification
 - Regression tests no longer require ksh
 - Renamed regress.sh to system_test.sh

== 2.7: February 12, 2014
 - Changed function pointer prefixes from '_' to 'x' to avoid runtime symbol
   collisions in libc. Required to build on DragonFlyBSD
 - Added this NEWS file to provide detailed release history for port maintainers
 - Subsitute '/_' argument with the first file that changed
 - Man page formatted with more semantically correct markup
 - Multiple events on the same file are merged on Linux to prevent duplicate
   writes to a named pipe

== 2.6: January 23, 2014
 - Added -c option to clear the screen before calling execvp(3)
 - Changed command line option '{}' to '/_'
 - Renamed Makefile.linux-lbsd to Makefile.debian
 - Include CPPFLAGS since some build systems (namely Debian) use it to specify
   hardening options
 - Raise ARG_MAX from 4K to 2MB on Linux, since _SC_ARG_MAX returns an incorrect
   value on Linux
 - Handle RENAME events that are not followed by DELETE. This enables us to cope
   with the backup option in Vim.

== 2.5: December 30, 2013
 - Restore full 50ms period for consolidating events on Linux. Required for the
   Geany editor
 - Remove use of setproctitle(3), no plans to implement this on Linux and MacOS.
   This also eliminates use of the 3-clause license
 - New feature: the first occurrence of '{}' on the command line will be
   replaced with the name of the first file under watch
 - Set PAGER to an absolute path (/bin/cat)
 - Prevent interactive utilities from paging output

== 2.4: December 18, 2013
 - Reintroduce ${DESTDIR} for STAGEDIR installation on FreeBSD and pkgsrc
 - License file describes the copyright holders for the compatibility libraries

== 2.3: December 12, 2013
 - Wait for processes to terminate in restart mode
 - Set process title for blocking events
 - Correct multiple bugs in the inotify->kqueue translation layer
 - Print out detailed instructions if the user provides configure arguments
 - Remove ${DESTDIR} from Makefile which appears to interfere with OpenBSD ports
 - The handler for SIGSEGV prints file name and line number if a unit test fails
 - Reduce the number of attempts to re-open files to 10 (total of 1 second)
 - Define architecture in Makefile instead of testing for __linux or __APPLE__

== 2.2: August 07, 2013
 - Process every delete or rename event to ensure files remain tracked
 - Always process DELETE or RENAME events to prevent a files from escaping watch
 - inotify(7) events are consolidated for a duration of 50ms as a workaround for
   an apparent  bug in glib/gio where a file is written and then removed
 - Execute mode can run a file under watch by retrying if text file is busy
 - Exit non-zero if list of regular files exceeds the hard limit set by the
   current login class
 - Ignore directories and special files; exit with error code 1 if no regular
   files are provided as input.

== 2.1: July 01, 2013
 - Zero-dependency build on Linux using built-in compatibility layer
 - Add poll with optional timeout in order to prevent change events from
   accumulating while running a command
 - Invalidate file->fd after inotify event is closed. Do not respond to
   IN_MOVE_SELF since this event only occurs on Linux NFS mounts
 - Optional build on GNU/Linux using external compatibility libraries libkqueue
   and libbsd
 - Fix bug in finding the correct filename to write to a FIFO
 - Correct build on MacOS

== 2.0: June 17, 2013
 - Support for old architectures without C99 support
 - More aggressively remove duplicate events
 - install/uninstall uses DESTDIR to be compatible with pkgsrc
