Function naming

• <name>_new() functions allocates and initialize an instance of a struct named <name>.
• <name>_storage_new(...) allocates and initialize an instance of a structure named <name> and pre-allocates internal content in a single allocation.
• <name>_init(<name> *instance) Initialize an instance of <name> with the default values. These functions should be called only once on instance allocated on stack.
• <name>_clear(<name> instance *) resets instance members to their initial state.
• <name>_free(<name> instance **) Free an instance memory previously allocated with <name>_new() and sets the pointer value to NULL
• *_consume functions read the given input text looking for HTTP message entities and returns the number of bytes consumed on success or a negative error code on failure.
• *_write_* functions copy the content of a HTTP message entity to a target and returns the number of bytes written on success or a negative value on error. *
