* elilo 3.12 release commit
* Added additional #defines for debug levels to reduce the output
* Added Mac console patch rework from Julien Blache @ debian
this fixes the invisible console output from elilo on Macs
* Moved static ELILO_VERSION variable from elilo.c to elilo.h
so that elilo will print its version string and arch on startup.
* Fixed bug 2825044 ExitBootServices error handling, correctly deal
with changed memory map key if memory map changes from under elilo.
* Added memory map key to map debug output.
* Fixed bug 2874380 netbooting just flat broken. fixed ia64, x86_64
ia32, fixed handling of server side support of tfpt options (get file size)
elilo now attempts to get file size before attempting read of file
to set the buffers up correctly and deal with tftp servers that dont
support options extensions a little better.
* netboot, fixed bad blocksize handling
* netboot, fixed filename length for elilo-x86_64.conf type on tftp
server.
* increased bzimage kernel max length sizes to 4mb on i386 and 8mb on
x86_64... this is a legacy design hold over from original design and
needs to be re-written to do dynamic size memory management based on
the size of the actual vmlinuz image, as ia64/gzip does.

* Bumped version string to 3.10

* For read operations, the return data will be placed in the buffer specified by BufferPtr. If
* BufferSize is too small to contain the entire downloaded file, then
* EFI_BUFFER_TOO_SMALL will be returned and BufferSize will be set to zero or the size of
* the requested file (the size of the requested file is only returned if the TFTP server supports TFTP
* options). If BufferSize is large enough for the read operation, then BufferSize will be set to
* the size of the downloaded file, and EFI_SUCCESS will be returned. Applications using the
* PxeBc.Mtftp() services should use the get-file-size operations to determine the size of the
* downloaded file prior to using the read-file operations—especially when downloading large
* (greater than 64 MB) files—instead of making two calls to the read-file operation. Following this
* recommendation will save time if the file is larger than expected and the TFTP server does not
* support TFTP option extensions. Without TFTP option extension support, the client has to
* download the entire file, counting and discarding the received packets, to determine the file size.
* ...
* For TFTP “get file size” operations, the size of the requested file or directory is returned in
* BufferSize, and EFI_SUCCESS will be returned. If the TFTP server does not support options,
* the file will be downloaded into a bit bucket and the length of the downloaded file will be returned.

CHANGES FROM 3.8 TO 3.10
CHANGES FROM 3.10 TO 3.12
========================
Patch contributions from David Lombard @ Intel and Stuart Hayes @ Dell
thank you.
Patch contributions from Julen Blache @ Debian
thank you. ** ADDS MAC IA32 NATIVE BOOT SUPPORT (i.e. consplitter fix)
* added PTR_FMT 32bit & 64bit pointer translation for correct output
* elilo hang bugfix x86_64 non-standard kernels with non-traditional start
address elilo will pull the start address from the kernel elf header for 2.6
or newer kernels, map memory and use that start address, else use standard
1MB default start address. And handle case of overlapping kernels
and initrds in memory.
* ported kernel start adress and memory overlap handling to ia32
* eliminated all possible compiler warnings except those actually
caused by gnu-efi that cant be fixed here.
* Debug output improvement, added pauses with visual feedback when
user sets debug or verbose options.
* bugfix added missing find_bits function definition back into ia32
subtree
* bugfix loader_probe now correctly errors out if no loaders
registered.
* Added additional #defines for debug levels to reduce the output noise
* Added Mac console patch rework from Julien Blache @ debian
this fixes the invisible console output from elilo on Macs
* Moved static ELILO_VERSION variable from elilo.c to elilo.h
so that elilo will print its version string and arch on startup.
* Fixed bug 2825044 ExitBootServices error handling, correctly deal
with changed memory map key if memory map changes from under elilo.
* Added memory map key to map debug output.
* Fixed bug 2874380 netbooting just flat broken. fixed ia64, x86_64
ia32, fixed handling of server side support of tfpt options (get file size)
elilo now attempts to get file size before attempting read of file
to set the buffers up correctly and deal with tftp servers that dont
support options extensions a little better.
* netboot, fixed bad blocksize handling
* netboot, fixed filename length for elilo-x86_64.conf type on tftp
server.
* increased bzimage kernel max length sizes to 4mb on i386 and 8mb on
x86_64... this is a legacy design hold over from original design and
needs to be re-written to do dynamic size memory management based on
the size of the actual vmlinuz image, as ia64/gzip does.
