[realtek] Support RTL8139 cards within generic Realtek driver
RTL8139C+ cards use essentially the same datapath as RTL8169, which is
zerocopy and 64-bit capable. Older RTL8139 cards use a single receive
ring buffer rather than a descriptor ring, but still share substantial
amounts of functionality with RTL8169.
Include support for RTL8139 cards within the generic Realtek driver,
since there is no way to differentiate between RTL8139 and RTL8139C+
cards based on the PCI IDs alone.
Many thanks to all the people who worked on the rtl8139 driver over
the years.

[crypto] Do not allow build-time cryptography settings to be overridden
If a root certificate has been explicitly specified at build time
using TRUST=/path/to/cert then do not allow this to be overridden even
from a trustworthy settings source (such as VMware GuestInfo).
Similarly, if a client certificate (and private key) has been
explicitly specified at build time, then do not allow it to be
overridden at runtime.

[build] Use $(xxx_DEPS) for additional dependency information
Some objects (embedded.o, rootcert.o, and clientcert.o) define
additional dependencies on external files, using syntax such as:
$(BIN)/clientcert.o : $(CERT_LIST)
This dependency can be missed when using debug builds. For example,
if DEBUG=clientcert is used, then the relevant object is
$(BIN)/clientcert.dbg1.o rather than $(BIN)/clientcert.o.
Fix by adding dependencies to $(clientcert_DEPS) instead:
clientcert_DEPS += $(CERT_LIST)

[http] Avoid using stack-allocated memory in http_step()
http_step() allocates a potentially large block of storage (since the
URI can be arbitrarily long), and can be invoked as part of an already
deep call stack via xfer_window_changed().

[xfer] Avoid using stack-allocated memory in xfer_printf()
xfer_printf() occasionally has to deal with strings that are
potentially long, such as HTTP URIs with multiple query parameters.
Allocating these on the stack can lead to stack overruns and memory
corruption.
Fix by using vasprintf() instead of a stack allocation.

The link state is currently set at probe time, and updated only when
the device is polled. This results in the user seeing a misleading
stale "Link: down" message, if autonegotiation did not complete within
the short timespan of the probe routine.
Fix by updating the link state when the device is opened, so that the
message that ends up being displayed to the user reflects the real
link state at device open time.

[netdevice] Allow network device to update link state before checking
If the network interface has only just been opened (e.g. by the "dhcp"

There is no explicit SNP API call to determine link state; the SNP

[crypto] Allow trusted root certificate to be changed without a rebuild
Changing the trusted root certificate currently requires a rebuild of
the iPXE binary, which may be inconvenient or impractical.
Allow the list of trusted root certificate fingerprints to be
overridden using the "trust" setting, but only at the point of iPXE
initialisation. This prevents untrusted sources of settings
(e.g. DHCP) from subverting the chain of trust, while allowing
trustworthy sources to change the trusted root certificate without
requiring a rebuild.
The basic idea is that if you are able to manipulate a trustworthy
source of settings (e.g. VMware GuestInfo or non-volatile stored
options), then you would be able to replace the iPXE binary anyway,
and so no security is lost by allowing such sources to override the
list of trusted root certificates.

Solaris assumes that there is enough space above the Multiboot modules
to use as a decompression and scratch area. This assumption is
invalid when using iPXE, which places the Multiboot modules near the
top of (32-bit) memory.
Fix by copying the modules to an area of memory immediately following
the loaded kernel.

[util] Add utility to generate list of supported network cards
niclist.pl recursively scans specified source folders and builds a
list of supported NICs by looking for ISA_ROM and PCI_ROM lines and
outputs the list in text, CSV, JSON, HTML or DokuWiki format. Sorting
and column selection is possible.
The pci-utils pci.ids file is fetched from SourceForge once a day to
also output the "official" vendor/device names associated with the PCI
device.
