9acd41a942 Reworked the stepper routine: 
1) The computational load is spread more evenly along the stepper ISR
ticks by moving some of the timer and linear advance calculation from
the block initialization into the 1st tick of the steady phase
of the trapezoid.

2) Reworked planning of the Linear Advance ISR ticks to fit
the time slot allocated for the main stepper ISR tick. This is achieved
by grouping the Linear Advance extruder ticks by a power of two to tick
the Linear Advance interrupts at a maximum 7kHz. Also some
of the extruder ticks are performed just after the XYZ ticks
and if the remaining time slot for the Linear Advance ticks is too short,
all the Linear Advance steps are ticked inside the main stepper ISR invocation.

3) Added some calls to MSerial.checkRx() if the stepper ISR routine
is delayed for too long by the additional LinearAdvance ticks.

This implementation differs significantly from the original implementation
by @Sebastianv650, as this implementation tries to follow the exact
timing of the XYZ axes with the drawback of possibly ticking the extruder
faster than it could handle, while the original implementation
by @Sebastianv650 ticks the extruder slower with the drawback of possibly
spreading the XYZ ticks, thus introducing jerk in the cartesian movement.

c2950b01a6 Added macros for outputting serial data onto the logical analyzer line 
at 2 megabaud, 9bits, 1 stop bit. At this high rate the serial output
takes next to no time, so it does not slow down the debugged firmware
too much, and the data is nicely aligned with the other debug signals
on the logical analyzer screen.

3b312a42f8 Adjusted the features for the debug buid: 
Removed DEBUG_DISABLE_STARTMSGS. This macro defeats the purpose
of the build server and the build messages of the non-release builds.

Removed DEBUG_DUMP_TO_2ND_SERIAL for performance reasons.

485355274e Optimized the MarlinSerial class by declaring all methods static. 
The MarlinSerial defines no member variable, though the AVR GCC
stored a "this" pointer onto stack when calling the non-static
methods anyway.
