/**
 * Optionally do reassembly of the request/response line, headers, and body.

 *  @param tvb  The buffer.
 *  @param offset   The offset in the buffer to begin inspection.
 *  @param pinfo    Packet info from the parent protocol.
 *  @param desegment_headers    Do desegmentation on headers.
 *  @param desegment_body   Do desegmentation on body.
 *  @param desegment_until_fin  When desegment_body is enabled and no
 *  Content-Length header is found, assume that all data following the headers
 *  are part of the body.
 *  @param[in,out] last_chunk_offset  For the chunked Transfer-Encoding,
 *  the offset (relative to the initial tvb offset) of the last chunk size
 *  found.  The result can be fed back into a future call in order to skip
 *  to a later chunk and reduce processing from O(N^2) to O(N).  Use 0 for
 *  the initial call.  Only set when chunked TE is found.  May be NULL.
 *  @return TRUE if desegmentation is complete otherwise FALSE
