Add a centralised concept of colours and colour pairs (using the
default colour pairs as configured via config/colour.h). A colour
pair consists of a pair of colour indices.
Add the ability to redefine both a colour pair and an individual
colour index, with minimal overhead if this feature is not required
(e.g. because the relevant shell commands are not present in the
build).

Add support for the stateful and stateless variants of the DHCPv6
protocol. The resulting settings block is registered as
"net<x>.dhcpv6", and DHCPv6 options can be obtained using
e.g. "${net0.dhcpv6/23:ipv6}" to obtain the IPv6 DNS server address.
IPv6 addresses obtained via stateful DHCPv6 are not yet applied to the
network device.

Allow memory map entries to be read using the syntax
${memmap/<region>.<properties>.<scale>}
where <region> is the index of the memory region, <properties> is a
bitmask where bit 0 represents the start address and bit 1 represents
the length (allowing the end address to be encoded by having both bits
0 and 1 set), and <scale> is the number of bits by which to shift the
result.
This allows for several values of interest to be encoded. For
example:
${memmap/<region>.1.0:hexraw} # 64-bit start address of <region>
${memmap/<region>.2.0:hexraw} # 64-bit length of <region>, in bytes
${memmap/<region>.3.0:hexraw} # 64-bit end address of <region>
${memmap/<region>.2.10:int32} # Length of <region>, in kB
${memmap/<region>.2.20:int32} # Length of <region>, in MB
The numeric encoding is slightly more sophisticated than described
here, allowing a single encoding to cover multiple regions. (See the
source code for details.) The primary use case for this feature is to
provide the total system memory size (in MB) via the "memsize"
predefined setting.

Allow values to be read from PCI configuration space using the syntax
${pci/<busdevfn>.<offset>.<length>}
where <busdevfn> is the bus:dev.fn address of the PCI device
(expressed as a single integer, as returned by ${net0/busloc}),
<offset> is the offset within PCI configuration space, and <length> is
the length within PCI configuration space.
Values are returned in reverse byte order, since PCI configuration
space is little-endian by definition.

iPXE is fundamentally asynchronous in operation: some operations
continue in the background even after the foreground has continued to
a new task. For example, the closing FIN/ACK exchanges of a TCP
connection will take place in the background after an HTTP download
has completed.

ANS X9.82 specifies several Approved algorithms for use in a
Deterministic Random Bit Generator (DRBG). One such algorithm is
HMAC_DRBG, which can be implemented using the existing iPXE SHA-1 and
HMAC functionality. This algorithm provides a maximum security
strength of 128 bits.

For performing installations direct to a SAN target, it can be very
useful to hook a SAN disk and then proceed to perform a filename boot.
For example, the user may wish to hook the (empty) SAN installation
disk and then boot into the OS installer via TFTP. This provides an
alternative mechanism to using "keep-san" and relying on the BIOS to
fall through to boot from the installation media, which is unreliable
on many BIOSes.
When a root-path is specified in addition to a boot filename, attempt
to hook the root-path as a SAN disk before booting from the specified
filename. Since the root-path may be used for non-SAN purposes
(e.g. an NFS root mount point), ignore the root-path if it contains a
URI scheme that we do not support.
