Mark all files used in a standard build of bin-x86_64-efi/snponly.efi
as permitted for UEFI Secure Boot. These files represent the core
functionality of iPXE that is guaranteed to have been included in
every binary that was previously subject to a security review and
signed by Microsoft. It is therefore legitimate to assume that at
least these files have already been reviewed to the required standard
multiple times.

All consumers of profile_timestamp() currently treat the value as an
unsigned long. Only the elapsed number of ticks is ever relevant: the
absolute value of the timestamp is not used. Profiling is used to
measure short durations that are generally fewer than a million CPU
cycles, for which an unsigned long is easily large enough.
Standardise the return type of profile_timestamp() as unsigned long
across all CPU architectures. This allows 32-bit architectures such
as i386 and riscv32 to omit all logic associated with retrieving the
upper 32 bits of the 64-bit hardware counter, which simplifies the
code and allows riscv32 and riscv64 to share the same implementation.

As with assertions, profiling is enabled for objects built with any
debug level (including an explicit debug level of zero).
Allow profiling to be globally enabled or disabled by adding PROFILE=1
or PROFILE=0 respectively to the build command line.

Provide profile_custom() as a trivial wrapper around profile_update()
to allow for the use of the profiling infrastructure by code using
timers other than the default profile_timestamp() provider.

Interrupt processing adds noise to profiling results. Allow
interrupts (from within protected mode) to be profiled separately,
with time spent within the interrupt handler being excluded from any
other profiling currently in progress.

Access to the gpxe.org and etherboot.org domains and associated
resources has been revoked by the registrant of the domain. Work
around this problem by renaming project from gPXE to iPXE, and
updating URLs to match.
Also update README, LOG and COPYRIGHTS to remove obsolete information.
