[DHCP] Save precious packet-aligned memory by copying DHCP responses
...
Copy DHCP responses to a standard malloc()ed buffer, rather than
retaining the I/O buffer that they arrived in.

[Settings] Remove assumption that all settings have DHCP tag values
...
Allow for settings to be described by something other than a DHCP option
tag if desirable. Currently used only for the MAC address setting.
Separate out fake DHCP packet creation code from dhcp.c to fakedhcp.c.
Remove notion of settings from dhcppkt.c.
Rationalise dhcp.c to use settings API only for final registration of the
DHCP options, rather than using {store,fetch}_setting throughout.

[DHCP] Fix up fake-packet creation as used by PXENV_GET_CACHED_INFO

Add dedicated functions create_dhcpdiscover(), create_dhcpack() and
create_proxydhcpack() for use by external code such as the PXE preboot
code.
Register ProxyDHCP options under the global scope "proxydhcp".
Unregister previously-acquired DHCP and ProxyDHCP settings when DHCP
succeeds.

[DHCP] Fix RFC4390 client identifier constructions.

RFC 4390 provides for the DHCP client identifier to contain the link-layer
hardware type and MAC address when the MAC address exceeds 16 bytes.
However, the hardware type field is only 8 bits; we were assuming 16 bits.

Gave asynchronous operations approximate POSIX signal semantics. This
...
will enable us to cascade async operations, which is necessary in order to
properly support DNS. (For example, an HTTP request may have to redirect
to a new location and will have to perform a new DNS lookup, so we can't
just rely on doing the name lookup at the time of parsing the initial
URL).
Anything other than HTTP is probably broken right now; I'll fix the others
up asap.
