[crypto] Allow an error margin on X.509 certificate validity periods
iPXE has no concept of the local time zone, mainly because there is no
viable way to obtain time zone information in the absence of local
state. This causes potential problems with newly-issued certificates
and certificates that are about to expire.
Avoid such problems by allowing an error margin of around 12 hours on
certificate validity periods, similar to the error margin already
allowed for OCSP response timestamps.

[dhcp] Request broadcast responses when we already have an IPv4 address
FCoE requires the use of multiple local unicast link-layer addresses.
To avoid the complexity of managing multiple addresses, iPXE operates
in promiscuous mode. As a consequence, any unicast packets with
non-matching IPv4 addresses are rejected at the IPv4 layer (rather
than at the link layer).
This can cause problems when issuing a second DHCP request: if the
address chosen by the DHCP server does not match the existing address,
then the DHCP response will itself be rejected.
Fix by requesting a broadcast response from the DHCP server if the
network interface already has any IPv4 addresses.

[romprefix] Treat 0xffffffff as an error return from PMM
PMM defines the return code 0xffffffff as meaning "unsupported
function". It's hard to imagine a PMM BIOS that doesn't support
pmmAllocate(), but apparently such things do exist.

[romprefix] Allow .mrom image to be placed anywhere within the BAR
A .mrom image currently assumes that it is the first image within the
expansion ROM BAR, which may not be correct when multiple images are
present.
Fix by scanning through the BAR until we locate an image matching our
build ID.

[romprefix] Add a dummy ROM header to cover the .mrom payload
The header of a .mrom image declares its length to be only a few
kilobytes; the remainder is accessed via a sideband mechanism. This
makes it difficult to append an additional ROM image, such as an EFI
ROM.
Add a second, dummy ROM header covering the payload portion of the
.mrom image, allowing consumers to locate any appended ROM images in
the usual way.

Add "sync" command (loosely based on the Unix "sync"), which will wait

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.

[http] Defer processing response code until after receiving all headers
Some headers can modify the meaning of the response code. For
example, a WWW-Authenticate header can change the interpretation of a
401 Unauthorized response from "Access denied" to "Please
authenticate".

[crypto] Rename KEY= to PRIVKEY= and "key" to "privkey"

[efi] Work around platforms which choke on EFI_PCI_DEVICE_ENABLE
EFI_PCI_DEVICE_ENABLE is a list of the standard attributes that must
be enabled for a PCI device to function: I/O cycles, memory cycles,
and bus-mastering. We currently call EFI_PCI_IO_PROTOCOL::Attribute()
with the parameter EFI_PCI_DEVICE_ENABLE to enable a PCI device. This
should translate to a single write to PCI configuration space.
Simplicity is not a virtue within the UEFI world. Some platforms will
'helpfully' report an error if EFI_PCI_DEVICE_ENABLE is used on a
device that doesn't actually support all three of the relevant
attributes. For example, if a PCI device provides only memory-mapped
accesses (and so hardwires the I/O enable bit to zero), then using
EFI_PCI_DEVICE_ENABLE on such a platform will result in an
EFI_UNSUPPORTED error.
There is no plausible use case in which it is useful for the platform
to return an error in this way, and doing so makes it impossible to
distinguish genuine errors from noise.
Work around this broken behaviour by attempting to enable the three
attributes individually, and ignoring any errors.

iSCSI generally includes a full SCSI response only when an error
occurs. iscsi_scsi_done() currently passes the NULL response through
to scsi_response(), which ends up causing scsicmd_response() to
dereference a NULL pointer.
Fix by calling scsi_response() only if we have a non-NULL response.
