/***
RECEIVING COOKIE INFORMATION
============================
struct CookieInfo *cookie_init(char *file);
Inits a cookie struct to store data in a local file. This is always
called before any cookies are set.
int cookies_set(struct CookieInfo *cookie, char *cookie_line);
The 'cookie_line' parameter is a full "Set-cookie:" line as
received from a server.
The function need to replace previously stored lines that this new
line superceeds.
It may remove lines that are expired.
It should return an indication of success/error.
SENDING COOKIE INFORMATION
==========================
struct Cookies *cookie_getlist(struct CookieInfo *cookie,
char *host, char *path, bool secure);
For a given host and path, return a linked list of cookies that
the client should send to the server if used now. The secure
boolean informs the cookie if a secure connection is achieved or
not.
It shall only return cookies that haven't expired.
Example set of cookies:
Set-cookie: PRODUCTINFO=webxpress; domain=.fidelity.com; path=/; secure
Set-cookie: PERSONALIZE=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
domain=.fidelity.com; path=/ftgw; secure
Set-cookie: FidHist=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;
domain=.fidelity.com; path=/; secure
Set-cookie: FidOrder=none;expires=Monday, 13-Jun-1988 03:04:55 GMT;

* hostip.c explained
* ==================
*
* The main COMPILE-TIME DEFINES to keep in mind when reading the host*.c
* source file are these:
*
* CURLRES_IPV6 - this host has getaddrinfo() and family, and thus we use
* that. The host may not be able to resolve IPv6, but we don't really have to
* take that into account. Hosts that aren't IPv6-enabled have CURLRES_IPV4
* defined.
*
* CURLRES_ARES - is defined if libcurl is built to use c-ares for
* asynchronous name resolves. It cannot have ENABLE_IPV6 defined at the same
* time, as c-ares has no ipv6 support. This can be Windows or *nix.
*
* CURLRES_THREADED - is defined if libcurl is built to run under (native)
* Windows, and then the name resolve will be done in a new thread, and the
* supported API will be the same as for ares-builds.
*
* If any of the two previous are defined, CURLRES_ASYNCH is defined too. If
* libcurl is not built to use an asynchronous resolver, CURLRES_SYNCH is
* defined.
*
* The host*.c sources files are split up like this:
*
* hostip.c - method-independent resolver functions and utility functions
* hostasyn.c - functions for asynchronous name resolves
* hostsyn.c - functions for synchronous name resolves
* hostares.c - functions for ares-using name resolves
* hostthre.c - functions for threaded name resolves
* hostip4.c - ipv4-specific functions
* hostip6.c - ipv6-specific functions
*
* The hostip.h is the united header file for all this. It defines the
* CURLRES_* defines based on the config*.h and setup.h defines.
