Subject: [PATCH] [sanboot] Move keep-san setting out of iSCSI

The keep-san setting has been moved into a new sanboot.c file so that
SAN protocols other than iSCSI can access it.

Subject: [PATCH] [http] Add optional additional headers and other
changes

Support for optionally injecting additional headers into the HTTP
request,
which are passed by a caller of http_open_filter().  This can be useful
for
requesting byte ranges, for example.

Support for parsing Content-Range headers in responses.  If a caller to
http_open_filter() passes us a pointer to a resource length field, we
will
fill this field in on their behalf during processing.  Such a caller can
then know the total length of a resource, even if they only requested a
byte
range.

Subject: [PATCH] [httpdisk] HTTPDisk SAN protocol

A new, read-only SAN protocol.  If enabled for inclusion in the gPXE
build,
you can do something like:

sanboot http://shaomiller.com/test.hdd

in order to SAN-boot to an HDD image served from that web-site.
'keep-san'
should also preserve the SAN connection if the SAN's MBR code returns
control to gPXE.

This is handy for those who do not have AoE nor iSCSI services, but who
do have a web service.
