skip redundant calls to buffer_string_prepare_copy() when simply
clearing buffer is sufficient, e.g. when a blanked buffer is desired
before calling buffer_append_strftime(), which internally prepares
buffer for the resultant formatted string
connection_reset() is called at end of request to prepare for keep-alive
or to free resources while waiting for client to close connection.
This is the reason why it is called earlier towards end of request
rather than always waiting until the very end of request when socket
is closed.
connection_reset() used to additionally be called for every new socket
connection, but now is only called when new conns are allocated and
initialized.
replace my_bool with char in mod_vhostdb_mysql and mod_mysql_vhost
(mysql.h contains: typedef char my_bool; and passes a pointer to it
as third argument, a (void *), to mysql_options())
This use is not recommended since it means that the response body
will not contain the precise error code.

buffer_copy_string_len() and buffer_append_string_len() now
internally inline what buffer_commit() does, but do not repeat the
sanity checks already enforced by buffer_string_prepare_copy() and
buffer_string_prepare_append(), respectively
buffer_string_set_length() short-circuit common case
(missing HAVE_WOLFSSL_SSL_H without add_definition() suggests that
there are other definitions that are not being exported for use
in the build, so lighttpd built with CMake has base features only)
reject Transfer-Encoding from backend for mod_proxy.
mod_proxy currently sends HTTP/1.0 requests to the backend,
for which Transfer-Encoding: chunked is not a valid response header.
Additionally, there is no value to Transfer-Encoding: chunked from
backend since lighttpd mod_proxy sends HTTP/1.0 request along with
Connection: close, so the backend closing the socket is the end of
the response from the backend.

buffer_is_equal_caseless_string() now correctly matches against
the string only up to the provided string length, since the
string might not be '\0' terminated.
