This commit introduced the basic URI rewrite. It allows users to change request URI. Note the "rewrite" option ignores the contained query if any and the query from the request is preserverd.
An example:
"routes": [
    {
        "match": {
            "uri": "/v1/test"
        },
        "action": {
            "return": 200
        }
    },
    {
        "action": {
            "rewrite": "/v1$uri",
            "pass": "routes"
        }
    }
]

This removes a bunch of unused files that would have been touched by
subsequent commits that switch to using nxt_bool_t (AKA unit6_t) in
structures.

In auto/sources we have

  NXT_LIB_SRC0=" \
      src/nxt_buf_filter.c \
      src/nxt_job_file.c \
      src/nxt_stream_module.c \
      src/nxt_stream_source.c \
      src/nxt_upstream_source.c \
      src/nxt_http_source.c \
      src/nxt_fastcgi_source.c \
      src/nxt_fastcgi_record_parse.c \
  \
      src/nxt_mem_pool_cleanup.h \
      src/nxt_mem_pool_cleanup.c \
  "

None of these seem to actually be used anywhere (other than within
themselves). That variable is _not_ referenced anywhere else.

Also remove the unused related header files: src/nxt_buf_filter.h,
src/nxt_fastcgi_source.h, src/nxt_http_source.h, src/nxt_job_file.h,
src/nxt_stream_source.h and src/nxt_upstream_source.h

Also, these files do not seem to be used, no mention under auto/ or build/

  src/nxt_file_cache.c
  src/nxt_cache.c
  src/nxt_job_file_cache.c

src/nxt_cache.h is #included in src/nxt_main.h, but AFAICT is not
actually used.

With all the above removed

  $ ./configure --openssl --debug --tests && make -j && make -j tests &&
  make libnxt

all builds.

Buildbot passes.

NOTE: You may need to do a 'make clean' before the next build attempt.

Due to the need to replace our use of clone/__NR_clone on Linux with
fork(2)/unshare(2) for enabling Linux namespaces(7) to keep the
pthreads(7) API working.  Let's rename NXT_HAVE_CLONE to
NXT_HAVE_LINUX_NS, i.e name it after the feature, not how it's
implemented, then in future if we change how we do namespaces again we
don't have to rename this.

This commit enables the building of the cgroup code. This is only built
when the cgroupv2 filesystem is found.

If cgroupv2 support is found then

  cgroupv2: .................. YES

will be printed by ./configure
