(Prior to rev 30233 there was a check to make sure it was not negative. This
effectively puts that same check back in.)
Fixes the fuzz failure seen in https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=4083

est. Use g_ascii_strcasecmp() and g_ascii_strncasecmp(), and supply our
own versions if they're missing from GLib (as is the case with GLib
1.x).
In the code to build the list of named fields for Diameter, don't use
g_strdown(); do our own g_ascii_-style upper-case to lower-case mapping
in the hash function and use g_ascii_strcasecmp() in the compare
function.
We do this because there is no guarantee that toupper(), tolower(), and
functions that use them will, for example, map between "I" and "i" in
all locales; in Turkish locales, for example, there are, in both
upper case and lower case, versions of "i" with and without a dot, and
the upper-case version of "i" is "I"-with-a-dot and the lower-case
version of "I" is "i"-without-a-dot. This causes strings that should
match not to match.
This finishes fixing bug 2010 - an earlier checkin prevented the crash
(as there are other ways to produce the same crash, e.g. a bogus
dictionary.xml file), but didn't fix the case-insensitive string matching.

Adds const declarations to req_resp_hdrs_do_reassembly() and re-orders some actions to occur after tests which may decide that the actions were not required.

Enclosed is a patch with fixes problems with the desegmentation of chunked HTTP
message bodies.
...
Changing the value of pinfo->desegment_len to DESEGMENT_ONE_MORE_SEGMENT rather
than the current 1 or 2 seems to make everything work. (I'm kind of confused as
to why the headers resassembly code already used DESEGMENT_ONE_MORE_SEGMENT and
the body reassembly code did not).

if we dont have a content-length but we do have a keepalive in the header then we should not do reassemble-until-fin.
convert some tvb_get_String into tvb_get_ephemeral_string at the same time

there used to be a bug in tcp reassembly that even if the dissector only asked for x more bytes from the next segment the entire segment would still be added to reassembly.
this caused some issues when there was a new multisegment pdu that started at the end of the segment but this bug was fixed when tcp reassembly was refactored semi-recently.
there was also another "bug" in the http reassembly that it would only ask for one more byte at a time when doing reassembly.
this did work well however when we still had the bug in tcp reassembly but made wireshark become very very very slow once this tcp bug was fixed since it is very very very slow to reassemble a huge http pdu just one byte at a time.
this patch adds partial support (what we need for http which does not use tcp_dissect_pdus() ) for the desegmentation flag : DESEGMENT_ONE_MORE_SEGMENT and also to the http dissector so that reassembly of http headers spanning multiple semgents now become fast again

add required code to the http (and others) code in req_resp_hdrs.c to signal to tcp
when it wants a session to be reassembled to the FIN.
This is currently done for all HTTP packets where we have a Content-type in the header but no content-length.
