[image] Simplify image management commands and internal API
Remove the name, cmdline, and action parameters from imgdownload() and
imgdownload_string(). These functions now simply download and return
an image.
Add the function imgacquire(), which will interpret a "name or URI
string" parameter and return either an existing image or a newly
downloaded image.
Use imgacquire() to merge similar image-management commands that
currently differ only by whether they take the name of an existing
image or the URI of a new image to download. For example, "chain" and
"imgexec" can now be merged.
Extend imgstat and imgfree commands to take an optional list of
images.
Remove the arbitrary restriction on the length of image names.

[crypto] Force caller to provide temporary storage for modular calculations
bigint_mod_multiply() and bigint_mod_exp() require a fixed amount of
temporary storage for intermediate results. (The amount of temporary
storage required depends upon the size of the integers involved.)
When performing calculations for 4096-bit RSA the amount of temporary
storage space required will exceed 2.5kB, which is too much to
allocate on the stack. Avoid this problem by forcing the caller to
allocate temporary storage.

[test] Avoid using "static const" for test declarations
gcc will not warn about unused constant static variables. An unused
test declaration is almost certainly a bug, so ensure that warnings
are generated.

Separate out the list of self-tests from the self-test infrastructure.
This allows tests to be run individually. For example:
make bin/sha1_test.iso

NIST provides a set of known-answer tests for the Hash_DRBG algorithm,
which includes known answers for the derivation function Hash_df used
as part of Hash_DRBG. Hash_DRBG is not an Approved algorithm for ANS
X9.82, but the known answers for Hash_df (which is part of ANS X9.82)
can still be used as part of the conformance testing for ANS X9.82.

[test] Add a basic infrastructure for running self-tests
This self-test mechanism is inspired by Perl's Test::Simple and
similar modules. The aim is to encourage the use of self-tests by
making it as easy as possible to create self-test code

Testing BOFM involves gaining access to an IBM blade chassis, which is
often not practical. Provide a facility for testing BOFM
functionality outside of a real IBM blade context.

Access to the gpxe.org and etherboot.org domains and associated
resources has been revoked by the registrant of the domain. Work
around this problem by renaming project from gPXE to iPXE, and
updating URLs to match.
Also update README, LOG and COPYRIGHTS to remove obsolete information.

Currently, handling of URI escapes is ad-hoc; escaped strings are
stored as-is in the URI structure, and it is up to the individual
protocol to unescape as necessary. This is error-prone and expensive
in terms of code size. Modify this behavior by unescaping in
parse_uri() and escaping in unparse_uri() those fields that typically
handle URI escapes (hostname, user, password, path, query, fragment),
and allowing unparse_uri() to accept a subset of fields to print so
it can be easily used to generate e.g. the escaped HTTP path?query
request.

When the 16-bit segment registers are accessed using 32-bit instructions
the high order bytes are undefined on older CPUs. We now explicitly
zero the high order bytes when snapshotting the CPU state. This ensures
that the GDB stub reports consistent values for the segment registers.
This commit implements GDB over UDP. Using UDP is more complex than
serial and has required some restructuring.
The GDB stub is now built using one or both of GDBSERIAL and GDBUDP
config.h options.
To enter the debugger, execute the gPXE shell command:
gdbstub <transport> [<options>...]
Where <transport> is "serial" or "udp". For "udp", the name of a
configured network device is required:
gdbstub udp net0
The GDB stub listens on UDP port 43770 by default.
