#154 modparam support for "str" type

[Kennard White]

Add new type "STRLEN_PARAM" for modparam that maps to the "str" type of str.h.I don't know where docs for this interface is -- if someone will point me to them (in SVN tree), I'll patch the docs also. Also happy to change the keyword name if someone has better idea.

Hi Bogden,

See patch 3051083 for example of usage. That particular patch is change to rr module to add flow routing support, and is non-trivial (and my version has now forked substantially from SVN).

This STRLEN_PARAM patch would allow a lot of code clean up and more robust code in many modules (because the .len parameter is set correctly without manual code). But I haven't made much use of this feature -- doesn't make sense until support is in core, since it makes it impossible module-level patches to be accepted.

The set of patches 3040885 , 3042883, 3046433, 3051083 are to be evaluated and integrated for the next release - we need to evaluate the approach in regards to flow routing RFC.

Regards,
Bogdan
