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
connection_reset().
convert all log_error_write() to log_error() and pass (log_error_st *)
use con->errh in preference to srv->errh (even though currently same)
avoid passing (server *) when previously used only for logging (errh)
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)
provide standard types in first.h instead of base.h
provide lighttpd types in base_decls.h instead of settings.h
reduce headers exposed by headers for core data structures
do not expose <pcre.h> or <stdlib.h> in headers
move stat_cache_entry to stat_cache.h
reduce use of "server.h" and "base.h" in headers
More specific checks on contents of array lists. Each module using
lists now does better checking on the types of values in the list
(strings, integers, arrays/lists)
This helps prevent misconfiguration of things like cgi.assign,
fastcgi.server, and scgi.server, where source code might be
served as static files if parenthesis are misplaced.

- 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.

* 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
buffer.
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
needed)
* refactor: create chunkqueue_steal: moving (partial) chunks into another
queue
* 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.

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

i hope it helps with merging stuff back to 1.5
