Hi all,

I have pushed out a prerelease of one of the development branches (I 
currently have three development branches open), 3.70-pre1.

This release revamps a whole lot of internal APIs to support reading 
files without knowing their length ahead of time.  This is necessary in 
order to support network protocols which do not advertise the transfer size.

The immediate user-visible change is that TFTP no longer requires the 
server to support the "tsize" option; this has the interesting 
consequence that it allows the use of a proxying TFTP server (e.g. a 
TFTP->HTTP proxy) without the proxy having to buffer the entire file.

The ultimate plan, however, is to move HTTP support into pxelinux 
itself.  There are a couple of potential paths for implementing this; 
the current plan is to do a joint development project with the gPXE 
development team, to obtain a single product with all the features of 
gPXE and PXELINUX combined.  If that doesn't work out, however, I do 
have a backup plan.
