9ef7e5e3af Major rework of the ia64 loaders. The two primary objectives are:
1. Make libefi portable by removing ia64 specific code and build
   it on i386 and amd64 by default to prevent regressions. These
   changes include fixes and improvements over previous code to
   establish or improve APIs where none existed or when the amount
   of kluging was unacceptably high.
2. Increase the amount of sharing between the efi and ski loaders
   to improve maintainability of the loaders and simplify making
   changes to the loader-kernel handshaking in the future.

The version of the efi and ski loaders are now both changed to 1.2
as user visible improvements and changes have been made.

dc91b1990a Extend struct devdesc with a unit field, called d_unit. Promote the
device (kind) specific unit field to the common field. This change
allows a future version of libefi to work without requiring anything
more than what is defined in struct devdesc and as such makes it
possible to compile said version of libefi for different platforms
without requiring that those platforms have identical derivatives
of struct devdesc.

108e5926e2 Don't hardcode unit 0 for the current device if we're loaded from an
EFI file system. When booting from a CD and there's already an EFI
system partition on the disk, setting the current device to unit 0
will select the harddisk. This invariably breaks installing FreeBSD
when other operating systems have been installed before.

We obviously want to do the same when we're booting over the network.
Maybe later.

Based on a patch (from memory) from: arun

73e39b57bc Increase the block size for reading and writing from 8KB to 1MB and
introduce a preprocessor define for it. The larger block size
significantly speeds up the loading of the kernel.

63071c12c8 Finally fix loader completely for IA64. efifs_stat() wasn't setting
the S_IFREG bit for regular files.  This caused the path search code to
skip it when it finally did find the kernel (after the common/module.c
buffer overrun bug was fixed)

08a102c3c4 Don't blindly dereference f->f_devdata as if it's always a pointer to
an efi_devdesc structure. When we're netbooting, f->f_devdata holds
the address of the network socket variable. Dereferencing this caused
some very unpredictable behaviour, including proper functioning.
So, as a sanity check, we first make sure f->f_dev points to our
own devsw. If not, the open will fail before we use f->f_devdata.

This solves the netboot hangs I invariably got whenever I used the
latest toolchain to compile the EFI loader.

fb20752c1a Add a twiddle meter when reading from files. Gives me something to look
at when a kernel is loading from a floppy.
