definition (which is used by autoboot.c) from tftp.c to settings.c.

[settings] Split fetching and storing out of setting type handlers
Refactor setting type handlers to parse and format values, rather than
storing and fetching formatted values.

[multiboot] Include full image URI in command line
Solaris kernels seem to rely on having the full kernel path present in
the multiboot command line; if only the kernel name is present then
the boot fails with the error message
krtld: failed to open 'unix'

[tls] Fix wrong memset in function tls_clear_cipher
sizeof(cipherspec) is obviously wrong in this context, because it will
only zero the first 4 or 8 bytes (cipherspec is a pointer).
This problem was reported by cppcheck.

Using __from_text16() and __from_data16() in inline asm constraints
sometimes defeats gcc's ability to simplify expressions down to
compile-time constants.

iPXE's support for COMBOOT images is now quite outdated; it has not
kept up to date with changes in the COMBOOT API. The primary use for
COMBOOT seems to be for menuing support. Now that we have native iPXE
script-based menus, COMBOOT support can be gracefully retired (with
immense thanks to Daniel Verkamp for having successfully implemented
such an ambitious feature many years ago).

[console] Ignore unexpected keysyms when generating keyboard maps
I am unable to find any definitive documentation on how Linux keyboard
symbols work. In the absence of any documentation, I'm going to
assume that unexpected keysyms are harmless and should be ignored.

[umalloc] Unhide umalloc()ed memory region when there are no allocations
At present, we always hide an extra sizeof(struct external_memory), to
account for the header on the lowest allocated block. This header
ceases to exist when there are no allocated blocks remaining.

[console] Do not share ANSI escape context between lineconsole users
An ANSI escape sequence context cannot be shared between multiple

[console] Add "log message" console usage and an internal syslog() call
Provide an internal syslog() function (unrelated to the syslog
console) which can be used to create log messages with specified
priorities.
The build-time constant LOG_LEVEL can be used to select the minimum
required priority for log messages. Any messages that do not have a
sufficient priority will be ignored (and will be optimised away at
compile-time).
The default LOG_LEVEL is LOG_NONE.

[console] Exclude text-based UI output from logfile-based consoles

[console] Allow usage to be defined independently for each console
Add the concept of a "console usage", such as "standard output" or
"debug messages". Allow usages to be associated with each console
independently. For example, to send debugging output via the serial
port, while preventing it from appearing on the local console:
#define CONSOLE_SERIAL CONSOLE_USAGE_ALL
#define CONSOLE_PCBIOS ( CONSOLE_USAGE_ALL & ~CONSOLE_USAGE_DEBUG )
If no usages are explicitly specified, then a default set of usages
will be applied. For example:
#define CONSOLE_SERIAL
will have the same affect as
#define CONSOLE_SERIAL CONSOLE_USAGE_ALL

[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.

Trusted images may always be executed. Untrusted images may be
executed only if the current image trust requirement allows untrusted
images.
Images can be marked as trusted using image_trust(), and marked as
untrusted using image_untrust().
The current image trust requirement can be changed using
image_set_trust(). It is possible to make the change permanent, in
which case any future attempts to change the image trust requirement
will fail.
