Daryl McDaniel c96bf1ff2c StdLib: Fix compilation errors caused by previous commit of daConsole.c
Move functions da_ConFlush and da_ConClose to just before da_ConPoll so that
they are defined after any calls to them.

Replace da_ConFlush with the actual final implementation instead of the
initial version which was committed.

Daryl McDaniel 86f2165dc3 StdLib: Fix IIO_Write() to return the number of bytes consumed, not characters output.
Depending upon termios settings, writing to a terminal device may result in
many more characters being output than were in the buffer provided to the
IIO_Write() function.

IIO_Write() is supposed to return the number of BYTES written, not characters.
Since the provided buffer contains MBCS characters, there can be up to three
bytes per character.  Due to the expansion that may occur, "BYTES written"
is interpreted to mean the number of BYTES consumed from the MBCS buffer
provided as a parameter to IIO_Write.

These changes ensure that the correct number of characters are consumed from
the internal Output buffer and the correct number of BYTES consumed from the
buffer parameter are counted and returned.

Update copyright.
Fix some indentation and white space issues.
Improve comments for IIO_Write().
Add debugging instrumentation to count unconsumed data in the Input and Output buffers.
Modify IIO_Write() to:
  Accurately count input bytes CONSUMED.
  Consume only as many expanded (cooked) characters from the output buffer
  as were actually sent to the device.

Daryl McDaniel 24903bc48a StdLib: Some deployed versions of the Simple Text Input Protocol randomly return either NUL characters or Scan Codes when just typing normal text. These changes filter out NUL characters and make Scan Code and error handling more robust.

Include/sys/termios.h: Add CHAR_SUB and CHAR_ESC for translation of '^Z' and the Escape Scan Code into the EOF and ESC characters, respectively.

LibC/Uefi/Devices/Console/daConsole.c:  Add da_ConRawRead() function to simplify the read logic. Discard NUL characters from the input stream.  In Blocking mode, retry until a non-NUL character is received.  In NonBlocking mode, a NUL causes an EAGAIN error to be returned.  Translate the Escape Scan Code into an ESC character.  If Scan Codes are ignored, retry if in Blocking mode else return an EAGAIN error.  UnGetKey becomes a single wide character instead of a structure.
    Change da_Poll() to use da_ConRawRead().

LibC/Uefi/InteractiveIO/IIOutilities.c:  BUG fix.  Return the processed input character instead of the raw character.  Allows EOF propagation.

LibC/Uefi/InteractiveIO/CanonRead.c:  Enable EOF propagation.

Overflow doesn’t seem to generate a trap

The memory allocation tests will also fail, sometimes leaving all available memory consumed.

The correct output in the above example is:
Maximum exponent = 128
Maximum number = 3.40282347e+38
Overflow doesn't seem to generate a trap

The root cause is that all operations on values of Long or ULong type, within the gdtoa library, must be 32-bit operations.  A previous change replaced the Long and ULong definitions with INTN and UINTN, respectively.  While this is correct for a lot of Linux and NetBSD code, it was not correct for this library.

This fix reverts the definitions of ULong and Long back to 32-bit types.
A descriptive comment has also been added to the U union.
Additional white-space has been added to tidy up the definitions of the word0 and word1 macros.

Verified with Enquire.efi and the ISO/IEC C Library compliance Validation Suite.

The cast to (void**) is needed for the last parameter of the AllocatePool call in malloc().  This is because type CPOOL_HEAD** is not automatically promoted to void**, as required by AllocatePool().
 
This was originally addressed in SVN revision 15474 but removed again in 15664.

wcsrtombs:  The C Language standard, ISO/IEC 9899:199409, states that the wcsrtombs() function will stop before encountering the terminating NUL character only if Dest is NOT NULL.  This implies that if Dest is NULL, the Limit parameter will be ignored.  In order to avoid system hangs, if Dest is NULL a Limit value of ASCII_STRING_MAX is automatically used.  Also fixed a typo in the function header comment.

With these changes, StdLib now passes all of the C Language Standards Compliance Tests for ISO/IEC 9899:199409 (C95).

TAB characters are supported and, by default, are rendered as 8 spaces.  They will still be read as a single TAB character.
Both Canonical and Non-Canonical modes are supported.
If a terminal device is opened with O_TTY_INIT in the mode, the device will be initialized to "sane" values for interactive use.  It will be in Canonical mode, Enter will be translated to NewLine and on output, a NewLine is translated to CRLF.  Echoing will be on, control characters are output as ^X, and TABs are expanded.
