Glenn Strauss 7c7f8c467c [multiple] split con, request (very large change)
NB: r->tmp_buf == srv->tmp_buf (pointer is copied for quicker access)

NB: request read and write chunkqueues currently point to connection
    chunkqueues; per-request and per-connection chunkqueues are
    not distinct from one another
      con->read_queue  == r->read_queue
      con->write_queue == r->write_queue

NB: in the future, a separate connection config may be needed for
    connection-level module hooks.  Similarly, might need to have
    per-request chunkqueues separate from per-connection chunkqueues.
    Should probably also have a request_reset() which is distinct from

avoid passing (server *) when previously used only for logging (errh)

Glenn Strauss f69bd9cdb8 [core] perf: simple, quick buffer_clear()
quickly clear buffer instead of buffer_string_set_length(b, 0) or
buffer_reset(b).  Avoids free() of large buffers about to be reused,
or buffers that are module-scoped, persistent, and reused.

(buffer_reset() should still be used with buffers in connection *con
 when the data in the buffers is supplied by external, untrusted source)

Stefan Bühler ad3e93ea96 Use buffer API to read and modify "used" member
- a lot of code tried to handle manually adding terminating zeroes and
  keeping track of the correct "used" count.
  Replaced all "external" usages with simple wrapper functions:
  * buffer_string_is_empty (used <= 1), buffer_is_empty (used == 0);
    prefer buffer_string_is_empty
  * buffer_string_set_length
  * buffer_string_length
  * CONST_BUF_LEN() macro
- removed "static" buffer hacks (buffers pointing to constant/stack
  memory instead of malloc()ed data)
- buffer_append_strftime(): refactor buffer+strftime uses
- li_tohex(): no need for a buffer for binary-to-hex conversion:
  the output data length is easy to predict
- remove "-Winline" from extra warnings: the "inline" keyword just
  supresses the warning about unused but defined (static) functions;
  don't care whether it actually gets inlined or not.

Stefan Bühler 6afad87d2e fix buffer, chunk and http_chunk API
* remove unused structs and functions
    (buffer_array, read_buffer)
  * change return type from int to void for many functions,
    as the return value (indicating error/success) was never checked,
    and the function would only fail on programming errors and not on
    invalid input; changed functions to use force_assert instead of
    returning an error.
  * all "len" parameters now are the real size of the memory to be read.
    the length of strings is given always without the terminating 0.
  * the "buffer" struct still counts the terminating 0 in ->used,
    provide buffer_string_length() to get the length of a string in a
    unset config "strings" have used == 0, which is used in some places
    to distinguish unset values from "" (empty string) values.
  * most buffer usages should now use it as string container.
  * optimise some buffer copying by "moving" data to other buffers
  * use (u)intmax_t for generic int-to-string functions
  * remove unused enum values: UNUSED_CHUNK, ENCODING_UNSET
  * converted BUFFER_APPEND_SLASH to inline function (no macro feature
  * refactor: create chunkqueue_steal: moving (partial) chunks into another
  * http_chunk: added separate function to terminate chunked body instead of
    magic handling in http_chunk_append_mem().
    http_chunk_append_* now handle empty chunks, and never terminate the
    chunked body.

Stefan Bühler 6f208cfde1 fix/silence bugs reported by ccc-analyzer (clang)
These should all be non critical:
 * memory leaks on startup in error cases (which lead to
   immediate shutdowns anyway)
 * http_auth/ldap: passing uninitialized "ret" to ldap_err2string
 * sizeof(T) not matching the target pointer in malloc/calloc calls;
   those cases were either:
   * T being the wrong pointer type - shouldn't matter as long as all
     pointers have same size
   * T being larger than the type needed
 * mod_accesslog: direct use after free in cleanup (server shutdown);
   could crash before "clean" shutdown
 * some false positives (mod_compress, mod_expire)
 * assert(srv->config_context->used > 0); - this is always the case,
   as there is always a global config block
