*
* formparse()
*
* Reads a 'name=value' parameter and builds the appropriate linked list.
*
* Specify files to upload with 'name=@filename', or 'name=@"filename"'
* in case the filename contain ',' or ';'. Supports specified
* given Content-Type of the files. Such as ';type=<content-type>'.
*
* If literal_value is set, any initial '@' or '<' in the value string
* loses its special meaning, as does any embedded ';type='.
*
* You may specify more than one file for a single name (field). Specify
* multiple files by writing it like:
*
* 'name=@filename,filename2,filename3'
*
* or use double-quotes quote the filename:
*
* 'name=@"filename","filename2","filename3"'
*
* If you want content-types specified for each too, write them like:
*
* 'name=@filename;type=image/gif,filename2,filename3'
*
* If you want custom headers added for a single part, write them in a separate
* file and do like this:
*
* 'name=foo;headers=@headerfile' or why not
* 'name=@filemame;headers=@headerfile'
*
* To upload a file, but to fake the file name that will be included in the
* formpost, do like this:
*
* 'name=@filename;filename=/dev/null' or quote the faked filename like:
* 'name=@filename;filename="play, play, and play.txt"'
*
* If filename/path contains ',' or ';', it must be quoted by double-quotes,
* else curl will fail to figure out the correct filename. if the filename
* tobe quoted contains '"' or '\', '"' and '\' must be escaped by backslash.
*
* This function uses curl_formadd to fulfill it's job. Is heavily based on
* the old curl_formparse code.
