On the sysmoBTS (ARM7TDMI) the parsing of a simple response
with quoted string takes up to 200ms. Parsing the single
digest line takes 40ms itself. Create a custom parser to
speed things up to avoid the backtracking between three
optional parsers that are combined in a choice.
A rule like "ANY star / quoted_string" will only parse the ANY
rules for '0' times. Change the order to avoid this and add a
small test that we properly parse the From address now.
token requires the presence of at least one match. The usage of
star has been wrong and is corrected now. This was seen due not
being able to parse a From address that included a diplay name.
Remove the trailing ";" to fix the parsing bug.
Add a testcase for testing ProxyAuthenticate and ProxyAuthorize,
extend the grammar and parser to handle the needed bits. Document
another error/failure with the dialog handling code and create a
testcase that fully connects a call.
We must extend the grammar to add caseInsensitive to a lot of
fields as they are case-insensitive as part of the specification
this even applies to some parameter names where expires and
eXpiReS are considered to be the same. Start with the simple
case of the parameter.
