Add FILE_LICENCE declarations to almost all files that make up the
various standard builds of gPXE.

Using "lret $2" to return from an interrupt causes interrupts to be
disabled in the calling program, since the INT instruction will have
disabled interrupts. Instead, patch CF on the stack and use iret to
return.
Interestingly, the original PC BIOS had this bug in at least one
place.

The PXE 1.x spec specifies that on NBP entry or on return from INT
1Ah AX=5650h, EDX shall point to the physical address of the PXENV+
structure. The PXE 2.x spec drops this requirement, simply stating
that EDX is clobbered. Given the principle "be conservative in what
you send, liberal in what you accept", however, we should implement
this anyway.

Try to avoid future problems caused by implicit section flags and/or
type information by instituting a policy that all .section
declarations must explicitly state the flags and type.
Most of this change was achieved using
perl -pi \
-e 's/".text"$/".text", "ax", \@progbits/ ; ' \
-e 's/".text16"$/".text16", "ax", \@progbits/ ; ' \

Reduce the number of sections within the linker script to match the
number of practical sections within the output file.
Define _section, _msection, _esection, _section_filesz, _section_memsz,
and _section_lma for each section, replacing the mixture of symbols that
previously existed.
In particular, replace _text and _end with _textdata and _etextdata, to
make it explicit within code that uses these symbols that the .text and
.data sections are always treated as a single contiguous block.

Wyse Streaming Manager server (WLDRM13.BIN) assumes that the PXENV+
entry point is at UNDI_CS:0000; apparently, somebody at Wyse has
difficulty distinguishing between the words "may" and "must"...
Add a dummy entry point at UNDI_CS:0000, which just jumps to the
correct entry point.

IBM's iSCSI Firmware Initiator checks the UNDIROMID pointer in the
!PXE structure that gets created by the UNDI loader. We didn't
previously fill this value in.
