/*
* Nasty internal details ahead...
*
* File curl_memory.h must be included by _all_ *.c source files
* that use memory related functions strdup, malloc, calloc, realloc
* or free, and given source file is used to build libcurl library.
* It should be included immediately before memdebug.h as the last files
* included to avoid undesired interaction with other memory function
* headers in dependent libraries.
*
* There is nearly no exception to above rule. All libcurl source
* files in 'lib' subdirectory as well as those living deep inside
* 'packages' subdirectories and linked together in order to build
* libcurl library shall follow it.
*
* File lib/strdup.c is an exception, given that it provides a strdup
* clone implementation while using malloc. Extra care needed inside
* this one.
*
* The need for curl_memory.h inclusion is due to libcurl's feature
* of allowing library user to provide memory replacement functions,
* memory callbacks, at runtime with curl_global_init_mem()
*
* Any *.c source file used to build libcurl library that does not
* include curl_memory.h and uses any memory function of the five
* mentioned above will compile without any indication, but it will
* trigger weird memory related issues at runtime.
*
* OTOH some source files from 'lib' subdirectory may additionally be
* used directly as source code when using some curlx_ functions by
* third party programs that don't even use libcurl at all. When using
* these source files in this way it is necessary these are compiled
* with CURLX_NO_MEMORY_CALLBACKS defined, in order to ensure that no
* attempt of calling libcurl's memory callbacks is done from code
* which can not use this machinery.
*
* Notice that libcurl's 'memory tracking' system works chaining into
* the memory callback machinery. This implies that when compiling
* 'lib' source files with CURLX_NO_MEMORY_CALLBACKS defined this file
* disengages usage of libcurl's 'memory tracking' system, defining
* MEMDEBUG_NODEFINES and overriding CURLDEBUG purpose.
*
* CURLX_NO_MEMORY_CALLBACKS takes precedence over CURLDEBUG. This is
* done in order to allow building a 'memory tracking' enabled libcurl
* and at the same time allow building programs which do not use it.
*
* Programs and libraries in 'tests' subdirectories have specific
* purposes and needs, and as such each one will use whatever fits
* best, depending additionally whether it links with libcurl or not.
*
* Caveat emptor. Proper curlx_* separation is a work in progress
* the same as CURLX_NO_MEMORY_CALLBACKS usage, some adjustments may
* still be required. IOW don't use them yet, there are sharp edges.

* FormAdd()
*
* Stores a formpost parameter and builds the appropriate linked list.
*
* Has two principal functionalities: using files and byte arrays as

* (as the user requests) while for files only the filename and not the
* content is stored.
*
* While you may have only one byte array for each name, multiple filenames
* are allowed (and because of this feature CURLFORM_END is needed after
* using CURLFORM_FILE).
*
* Examples:
*
* Simple name/value pair with copied contents:
* curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
* CURLFORM_COPYCONTENTS, "value", CURLFORM_END);
*
* name/value pair where only the content pointer is remembered:
* curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
* CURLFORM_PTRCONTENTS, ptr, CURLFORM_CONTENTSLENGTH, 10, CURLFORM_END);
* (if CURLFORM_CONTENTSLENGTH is missing strlen () is used)
*
* storing a filename (CONTENTTYPE is optional!):
* curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
* CURLFORM_FILE, "filename1", CURLFORM_CONTENTTYPE, "plain/text",
* CURLFORM_END);
*
* storing multiple filenames:
* curl_formadd (&post, &last, CURLFORM_COPYNAME, "name",
* CURLFORM_FILE, "filename1", CURLFORM_FILE, "filename2", CURLFORM_END);
*
* Returns:
* CURL_FORMADD_OK on success
* CURL_FORMADD_MEMORY if the FormInfo allocation fails
* CURL_FORMADD_OPTION_TWICE if one option is given twice for one Form
* CURL_FORMADD_NULL if a null pointer was given for a char
* CURL_FORMADD_MEMORY if the allocation of a FormInfo struct failed
* CURL_FORMADD_UNKNOWN_OPTION if an unknown option was used
* CURL_FORMADD_INCOMPLETE if the some FormInfo is not complete (or error)
* CURL_FORMADD_MEMORY if a HttpPost struct cannot be allocated
* CURL_FORMADD_MEMORY if some allocation for string copying failed.

* 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. 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
* hostip4.c - IPv4 specific functions
* hostip6.c - IPv6 specific functions
*
* The two asynchronous name resolver backends are implemented in:
* asyn-ares.c - functions for ares-using name resolves
* asyn-thread.c - functions for threaded name resolves
* The hostip.h is the united header file for all this. It defines the
* CURLRES_* defines based on the config*.h and curl_setup.h defines.
