A bunch of changes from Petr Lampa that add transparent proxy support to tinyproxy. The additional code is in process_request(), but Petr also had to change around some of the other functions (like process_client_headers and handle_connection.) Note: Right now this code has not been tested, but it is believed to work. To enable run ./configure --enable-transparent-proxy

(process_server_headers): Since we're stripping off the carriage return and newline, we need to add them back on when sending the response header to the client.

(add_header_to_connection): Removed the "double_cgi" boolean, since tinyproxy now ignores all the headers after a "double CGI" situation has occurred.
...
(get_all_headers): Instead of dropping duplicate headers when the "double CGI" situation occurs, tinyproxy will now drop _all_ the headers from the "inner" HTTP response.

(add_header_to_connection): Added a boolean to indicate that a "Double CGI" situation is in affect. This is needed to solve a problem with some sites (like cgi.ebay.com) where they are sending two HTTP response lines (and associated headers) with a response.
...
(get_all_headers): Detect if a "Double CGI" situation has occured.

Moved the definition of the struct buffer_s into the buffer.c file and out

of the buffer.h file. This also required the removal of the BUFFER_SIZE

Removed the request logging in the tunnel because it breaks the tunnel

concept since it blocks waiting for information from the client before any
data from the remote is relayed.

First change all the hashmap related calls to use the new API.

The remove_connection_headers() function now handles both the Connection

Fixed a couple of problems where tinyproxy was trying to free a memory

block which had not been allocated.
Also, the "proxy-connection" to the list of headers we don't pass.

Various code clean up. There is nothing new here, just mechanical changes

to the source to either remove code which is not needed, or consolidate
common code into a common section.

Changed the error boolean flag into a pointer to an error string and an

error code. We're storing this information because tinyproxy doesn't
output the error information until _after_ the client has sent it's
information.

processing functions. Also, added a list of headers to drop in the

Did a bit of consolidation by moving code into remove_connection_headers()
...
and added the get_content_length() function.
The process_server_headers() function was rewritten to remove the
Connection header correctly, and also retrieve the Content-Length value.
This value is needed in the relay_connection() function since there are
some remote machines which do not properly close down the connection once
the body has been retrieved. Thanks to James Flemer for finding a test
case for this problem.

the anonymous_search().

Fixed up a problem with X-Tinyproxy sending logic.

A _tonne_ of changes. It would almost be easier to just read the source
...
itself to find out all the changes. Changed the process_client_header()
function to use the hashmap and vector modules. I've made this change to
better handle the Connection header. The Connection header, it it's
present, lists all the headers which should _not_ be transmitted any
further along. An HTTP/1.1 proxy must respect this.
Other changes are basically cosmetic.

Redefined HTTP_LINE_LENGTH to be based on MAXBUFFSIZE (and set to around

Added the TUNNEL_CONFIGURED() macro to help with testing for the tunnel
support code.
Create the write_message() function to encapsulate the code which sends
the information to the file descriptor.
Moved the tunnel code into it's own function.

Added UPSTREAM_CONFIGURED() macro to help clean up the code.
...
Ignore any blank lines when tinyproxy is expecting a request line.
Instead of sending the request line to the remote server in pieces,
tinyproxy nows sends it in once go. This was done to fix a problem with
some sites like www.heise.de.
Changed all calls to connptr->ssl to connptr->connect_method.
Changed all calls to connptr->send_message to
connptr->send_response_message.
Moved the call to Via header code to inside to the tests to handle if
tinyproxy is sending an error message (don't need to send any headers.)

Changed the way relay_connection() works by having the both buffers

emptied when either socket is closed. This should be better for the tunnel
connections.
Change the connect_to_upstream() function to better utilize the
establish_http_connection() function. Code re-use is cool. :)
