[parser] third version of header and content parser

It was to complicated to use a pointer that may be reallocated
The "tempo" variable stores the length of data alreadey stored
for the "key" or "value".

The content parsing differs of the header a little:
 - the key/value separator is = instead :
 - the end of content is known by the content-length
