As part of the main conversion a few files were missed. These files had
additional whitespace after the '*' and before the SPDX tag and my
previous regex was too strict. This time I did a grep for all SPDX tags
and then filtered out anything that matched the correct styles.

If an event of a group event is signaled all other events of the same
group are signaled too.
Function efi_signal_event is renamed to efi_queue_event.
A new function efi_signal_event is introduced that checks if an event
belongs to a group and than signals all events of the group.
Event group notifciation is implemented for ExitBootServices,
InstallConfigurationTable, and ResetSystem.

In ExitBootServices we need to signal events irrespective of the current
TPL level. A new parameter check_tpl is added to efi_signal_event().
Function efi_console_timer_notify() gets some comments.

Use helper functions efi_created_handle and efi_add_protocol
for creating the console handles and instaling the respective
protocols.
This change is needed if we want to move from an array of
protocols to a linked list of protocols.
Eliminate EFI_PROTOCOL_OBJECT which is not used anymore.
Currently we have not defined protocol interfaces to be const.
So efi_con_out and efi_console_control cannot be defined as const.

Shell.efi uses this, and supporting color attributes makes things look
nicer. Map the EFI fg/bg color attributes to ANSI escape sequences.
Not all colors have a perfect match, but spec just says "Devices
supporting a different number of text colors are required to emulate the
above colors to the best of the device’s capabilities".

Queued and signaled describe boolean states of events.
So let's use type bool and rename the structure members to is_queued
and is_signaled.
Update the comments for is_queued and is_signaled.

once-per-string
2) handle \r, \t, and \b in addition to just \n for tracking
cursor position
3) cursor row/col are zero based, not one based

For the correct implementation of the task priority level (TPL)
calling the notification function must be queued.
Add a status field 'queued' to events.
In function efi_signal_event set status queued if a notification
function exists and reset it after we have called the function.
A later patch will add a check of the TPL here.
In efi_create_event and efi_close_event unset the queued status.
In function efi_wait_for_event and efi_check_event
queue the notification function.
In efi_timer_check call the efi_notify_event
if the status queued is set.
For all timer events set status signaled.
In efi_console_timer_notify set the signaled state of the
WaitForKey event.

Add support for EFI console modes.
Mode 0 is always 80x25 and present by EFI specification.
Mode 1 is always 80x50 and not mandatory.
Mode 2 and above is freely usable.
If the terminal can handle mode 1, we mark it as supported.
If the terminal size is greater than mode 0 and different than mode 1,
we install it as mode 2.
Modes can be switch with cout_set_mode.
Changes in V5:
Correctly detect mode before enabling mode 2.
Changes in V4:
Reset cursor positon on mode switch
Use local variables in console query code
Changes in V3:
Valid mode are 0 to EFIMode-1
Fix style
Changes in V2:
Add mode switch
Report only the modes that we support

One of the basic EFI interfaces is the console interface. Using it an EFI
application can interface with the user. This patch implements an EFI console
interface using getc() and putc().
Today, we only implement text based consoles. We also convert the EFI Unicode
characters to UTF-8 on the fly, hoping that everyone managed to jump on the
train by now.
