Add cleaned-up version of zeek-aux

This is the zeek-aux repository with all of the git-related stuff removed, including all of the pre-commit configuration files, git directories, and submodules. It has a modified version of the CMake configuration that uses Zeek's variables and paths, making zeek-aux effectively just a subdirectory to Zeek. All of the source files now have Zeek's license header in them as well.

+=======================
+Zeek Auxiliary Programs
+=======================
+
+.. contents::
+
+:Version: |version|
+
+Handy auxiliary programs related to the use of the Zeek Network Security
+Monitor (https://www.zeek.org).
+
+Installation
+============
+
+Installation is simple and standard::
+
+    ./configure
+    make
+    make install
+
+adtrace
+=======
+
+The "adtrace" utility is used to compute the
+network address that compose the internal and extern nets that Zeek
+is monitoring. This program just reads a pcap
+(tcpdump) file and writes out the src MAC, dst MAC, src IP, dst
+IP for each packet seen in the file.
+
+zeek-archiver
+=============
+
+This is a modern replacement for Zeek's historical log-archival process. For
+details, please refer to its dedicated README in the zeek-archiver subdirectory.
+
+zeek-cut
+========
+
+The "zeek-cut" utility reads ASCII Zeek logs on standard input
+and outputs them to standard output with only the specified columns (the
+column names can be found in each log file in the "#fields" header line).
+If no column names are specified, then "zeek-cut" simply outputs all columns.
+
+There are several command-line options available to modify the output (run
+"zeek-cut -h" to see a list of all options).  There are options to convert
+timestamps into human-readable format, and options to specify whether or not
+to include the format header lines in the output (by default, they're not
+included).
+
+For example, the following command will output the three specified columns
+from conn.log with the timestamps from the "ts" column being converted to
+human-readable format::
+
+    cat conn.log | zeek-cut -d ts id.orig_h id.orig_p
+
+The specified order of the column names determines the output order of the
+columns (i.e., "zeek-cut" can reorder the columns).
+
+The "zeek-cut" utility can read the concatenation of one or more uncompressed
+ASCII log files (however, JSON format is not supported) produced by Zeek
+version 2.0 or newer, as long as each log file contains format header
+lines (these are the lines at the beginning of the file starting with "#").
+In fact, "zeek-cut" can process the concatenation of multiple ASCII log files
+that have different column layouts.
+
+To read a compressed log file, a tool such as "zcat" must be used to
+uncompress the file.  For example, "zeek-cut" can read a group of compressed
+conn.log files with a command like this::
+
+    zcat conn.*.log.gz | zeek-cut
+
+
+devel-tools
+===========
+
+A set of scripts used commonly for Zeek development. Note that none of
+these scripts are installed by 'make install'.
+
+extract-conn-by-uid
+    Extracts a connection from a trace file based
+    on its UID found in Zeek's conn.log
+
+gen-mozilla-ca-list.rb
+    Generates list of Mozilla SSL root certificates in
+    a format readable by Zeek.
+
+update-changes
+    A script to maintain the CHANGES and VERSION files.
+
+git-show-fastpath
+    Show commits to the fastpath branch not yet merged into master.
+
+cpu-bench-with-trace
+    Run a number of Zeek benchmarks on a trace file.
+
+
+rst
+===
+
+The "rst" utility can be invoked by a Zeek script to terminate an
+established TCP connection by forging RST tear-down packets.

+Usage: $0 -z [zeek binary path] -d [data file path]
+
+  Options:
+    -b, --build PATH        The path to a Zeek binary to benchmark
+    -d, --data-file PATH    The path to a data file to read from for replay
+    -m, --mode MODE         This can be one of three possible values:
+                            intf, read, or flamegraph. This controls what
+                            mode is used for the benchmark run, and defaults
+                            to intf if not passed. The modes are described
+                            below.
+    -i, --interface INTF    The network interface to use for capturing data.
+                            This interface should be completely idle, since
+                            tcpreplay will be using it to replay the data.
+                            This argument is ignored if the mode is 'file'.
+    -f, --flamegraph PATH   The path to the directory where Flamegraph is
+                            installed. This argument is required if the mode
+                            is 'flamegraph', but is ignored otherwise.
+    -o, --output FILE       The file prefix to use as output for Flamegraph.
+                            This defaults to 'benchmark'. This argument is ignored
+                            if the mode is not 'flamegraph'.
+    -s, --seed FILE         (optional) A path to a Zeek random seed file.
+                            This is used control the generation of connection
+                            IDs and other data so it is consistent between
+                            benchmarking runs.
+
+    By default or when 'intf' is passed for the mode argument, the output will
+    include CPU, memory, etc statistics from Zeek processing all of the data
+    in the data file as if it was reading it live from the network. This mode
+    requires an interface to be passed using the -i argument.
+
+    When 'file' is passed for the mode (-m) argument, the output will include
+    the runtime and maximum memory usage of Zeek when reading the data file
+    directly from disk.
+
+    When 'flamegraph' is passed for the mode (-m) argument, this script will
+    output two flamegraphs for the process runtime in svg format. The first
+    flamegraph is a standard graph showing the time spent in functions,
+    stacked in the normal manner. The second graph is 'stack-reversed'.
+
+    Symbols in Flamegraph outputs may not correctly stack unless the various
+    libraries linked into Zeek are built with frame pointers. This includes
+    glibc, libpcap, and openssl. Rebuilding those libraries with the
+    -fno-omit-frame-pointer compiler flag may provide more accurate output.
+    You can set libraries that get preloaded by setting the PRELOAD_LIBS
+    variable in the script.
+
+    This script assumes that it is being run on a system with a large number
+    of CPU cores. If being used on a smaller system, modify this script and
+    set the ZEEK_CPU and TCPREPLAY_CPU variables to smaller values.

+
+zeek-cut [options] [<columns>]
+
+Extracts the given columns from ASCII Zeek logs on standard input, and outputs
+them to standard output. If no columns are given, all are selected.
+By default, zeek-cut does not include format header blocks in the output.
+
+Example: cat conn.log | zeek-cut -d ts id.orig_h id.orig_p
+
+    -c       Include the first format header block in the output.
+    -C       Include all format header blocks in the output.
+    -m       Include the first format header blocks in the output in minimal view.
+    -M       Include all format header blocks in the output in minimal view.
+    -d       Convert time values into human-readable format.
+    -D <fmt> Like -d, but specify format for time (see strftime(3) for syntax).
+    -F <ofs> Sets a different output field separator character.
+    -h       Show help.
+    -n       Print all fields *except* those specified.
+    -u       Like -d, but print timestamps in UTC instead of local time.
+    -U <fmt> Like -D, but print timestamps in UTC instead of local time.
+
+For time conversion option -d or -u, the format string can be specified by
+setting an environment variable ZEEK_CUT_TIMEFMT.
