Richard Barry 85fb1cc024 + New feature added: Task notifications.
+ Optimise Cortex-M4F ports by inlining some critical section macros.
+ Original ports used a #define to set the path to portmacro.h - that method has been obsolete for years and now all the old definitions have been moved into a separate header files called deprecated_definitions.h.
+ Cortex-M port now check the active vector bits against 0xff when determining if a function is called from an interrupt - previously only a subset of the bits (0x1f) were checked.
+ Add in new standard demo/test files TaskNotify.c/h and include the files in the simulator demos.
+ Update trace recorder code, and some demos to use the new version (more to do).
+ Introduce uxTaskPriorityGetFromISR().
+ Minor typo corrections.
+ Update MingW simulator demo to match the MSVC simulator demo.

* xTraceOpenLabel
*
* Creates user event labels for user event channels or for individual events.
* User events can be used to log application events and data for display in
* the visualization tool. A user event is identified by a label, i.e., a string,
* which is stored in the recorder's symbol table.
* When logging a user event, a numeric handle (reference) to this string is
* used to identify the event. This is obtained by calling
*
* xTraceOpenLabel()
*
* whihc adds the string to the symbol table (if not already present)
* and returns the corresponding handle.
*
* This can be used in two ways:
*
* 1. The handle is looked up every time, when storing the user event.
*
* Example:
* vTraceUserEvent(xTraceOpenLabel("MyUserEvent"));
*
* 2. The label is registered just once, with the handle stored in an
* application variable - much like using a file handle.
*
* Example:
* myEventHandle = xTraceOpenLabel("MyUserEvent");
* ...
* vTraceUserEvent(myEventHandle);
*
* The second option is faster since no lookup is required on each event, and
* therefore recommended for user events that are frequently
* executed and/or located in time-critical code. The lookup operation is
* however fairly fast due to the design of the symbol table.

* vTracePrintF
*
* Advanced user events (Professional Edition only)
*
* Generates User Event with formatted text and data, similar to a "printf".
* It is very fast compared to a normal "printf" since this function only
* stores the arguments. The actual formatting is done
* on the host PC when the trace is displayed in the viewer tool.
*
* User Event labels are created using xTraceOpenLabel.
* Example:
*
* traceLabel adc_uechannel = xTraceOpenLabel("ADC User Events");
* ...
* vTracePrint(adc_uechannel,
* "ADC channel %d: %lf volts",
* ch, (double)adc_reading/(double)scale);
*
* This can be combined into one line, if desired, but this is slower:
*
* vTracePrint(xTraceOpenLabel("ADC User Events"),
* "ADC channel %d: %lf volts",
* ch, (double)adc_reading/(double)scale);
*
* Calling xTraceOpenLabel multiple times will not create duplicate entries, but
* it is of course faster to just do it once, and then keep the handle for later
* use. If you don´t have any data arguments, only a text label/string, it is
* better to use vTraceUserEvent - it is faster.
*
* Format specifiers supported:
* %d - 32 bit signed integer
* %u - 32 bit unsigned integer
* %f - 32 bit float
* %s - string (is copied to the recorder symbol table)
* %hd - 16 bit signed integer
* %hu - 16 bit unsigned integer
* %bd - 8 bit signed integer
* %bu - 8 bit unsigned integer
* %lf - double-precision float (Note! See below...)
*
* Up to 15 data arguments are allowed, with a total size of maximum 32 byte.
* In case this is exceeded, the user event is changed into an error message.
*
* The data is stored in trace buffer, and is packed to allow storing multiple
* smaller data entries in the same 4-byte record, e.g., four 8-bit values.
* A string requires two bytes, as the symbol table is limited to 64K. Storing
* a double (%lf) uses two records, so this is quite costly. Use float (%f)
* unless the higher precision is really necessary.
*
* Note that the double-precision float (%lf) assumes a 64 bit double
* representation. This does not seem to be the case on e.g. PIC24 and PIC32.
* Before using a %lf argument on a 16-bit MCU, please verify that
* "sizeof(double)" actually gives 8 as expected. If not, use %f instead.
