[cmdline] Use "cpuid --ext" instead of "cpuid --amd"
Avoid potential confusion in the documentation by using a
vendor-neutral name for the extended (AMD-defined) feature set.

Add "sync" command (loosely based on the Unix "sync"), which will wait
for any pending operations to complete.

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] Provide credentials only when requested by server

401 Unauthorized response from the server.

[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"
The setting name "key" conflicts with the setting name "key" already
in use by the 802.11 code. Resolve the conflict by renaming the newer
setting 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.

X.509 certificate processing currently produces an overwhelming amount
of debugging information. Move some of this from DBGLVL_LOG to
DBGLVL_EXTRA, to make the output more manageable.

Automatically attempt to download any required cross-signing

To allow for automatic download of cross-signing certificates and for
OCSP, the validation of certificates must be an asynchronous process.
Create a stub validator which uses a job-control interface to report
the result of certificate validation.

CMS includes an unordered certificate set, from which certificates
must be extracted in order by matching up issuers with subjects. We
will use the same functionality as part of the automatic download of
cross-signing certificates. Generalise cms_find_subject() to
x509_find_subject(), and create x509_auto_append().
