Currently, our CcMapData() behavior (same goes for CcPinRead()) is broken
and is the total opposite of what Windows kernel does. By default, the later
will let you map a view in memory without even attempting to bring its
data in memory. On first access, there will be a fault and memory will
be read from the hardware and brought to memory. If you want to force read
on mapping/pinning, you have to set the MAP_NO_READ (or PIN_NO_READ) flag
where kernel will fault on your behalf (hence the need for MAP_WAIT/PIN_WAIT).
On ReactOS, by default, on mapping (and thus pinning), we will force a view
read so that data is in memory. The way our cache memory is managed at the
moment seems not to allow to fault on invalid access and if we don't force
read, the memory content will just be zeroed.
So trying to match Windows behavior, by default, now CcMapData() will enforce
the MAP_NO_READ flag and warn once about this behavior change.

- The default format is used when no format name is specified: this is
the one we use so far in ReactOS:
<debug_class>:(<file>:<line>) <message>
with "debug_class" being "trace", "warn", "err".
- The "wine" format is the one used by Wine. It can be used when trying
to diff-compare traces for a module with the corresponding one
obtained from a Wine run. It can also be useful because the logging of
Wine-synced code assumes that the function names are automatically
added by the helper macros "FIXME()", "TRACE()", "WARN()" or "ERR()",
and not manually inside the logging string given to these macros:
for example:
FIXME("(%params) message\n", params);
displays:
fixme:<module>:SomeFunc(params) message
- The "extended" (or "ext") format is very noisy and tries to output a
lot of information; it is a hybrid of the previous two formats:
<debug_class>:(<file>:<line>):<channel>:SomeFunc <message>
Support for displaying the current process ID is added in
addition to the already existing support for thread ID.
Google Chrome with -no-sandbox parameter in ReactOS wouldn't display the web page because first-chance exception raised.

- Remove FullName, Style, and FaceName members from TEXTOBJ structure.
- Add TextFace member into TEXTOBJ structure.
- Add MatchFontName() and MatchFontNames() helper functions.
- Fix GetTextFace() and related.
These macros should be implemented using the FsRtlTestAnsiCharacter() macro
that performs extended tests, especially for buffer overruns.
This fixes FsRtlIsAnsiCharacterWild(), FsRtlIsAnsiCharacterLegalFat(),
FsRtlIsAnsiCharacterLegalHpfs(), FsRtlIsAnsiCharacterLegalNtfs().
CORE-14067
Up to now, it was working by chance. Indeed, due to the invalid
ASCII check performed before calling FsRtlIsAnsiCharacterLegalHpfs(), the
macro is improperly called and overruns the FsRtlLegalAnsiCharacterArray
buffer. Fortunately, up to now, right after that buffer in kernel binary
there are strings which are more or less consistent with the flags that
are expected by the macro, causing a decent behavior of
FsRtlIsAnsiCharacterLegalHpfs() even for extended ASCII characters
(whereas FsRtlIsAnsiCharacterLegalHpfs() is only designed for ASCII
characters). But this is a totally out of control and wrong behavior.
A single change in the way the kernel was built could have caused the
CDFS driver not to work as previously.
I have made the choice to allow any extended ASCII character as done
for the unicode characters. This is a good compromise to avoid drastic
regressions for users having extended ASCII characters in their CD
file names.

- Simplify the usage of the PUPDATE_PROGRESS callback.
- Add the possibility of specifying an initial non-zero StepCount when
creating the progress-bar (using the -Ex version), so that it can be
initially drawn with the expected initial count.
Of course ProgressSetStepCount() can continue to be used.
It's based on the code that was in CcPinRead() implementation. This
made no sense to have CcPinMappedData() doing nothing while implementing
everything in CcPinRead(). Indeed, drivers (starting with MS drivers)
can map data first and pin it afterwards with CcPinMappedData(). It was
leading to incorrect behavior with our previous noop implementation.
