note on __attribute__ ((nocommon))
AVR scripts often use --gc-sections on the linker to remove unused section.
This works fine for initialed data and text sections. In principle .bss is also
handled, but the name##_pb definition is not removed. Reason is, that
array definitions are placed in the COMMON section, by default
The attribute "nocommon" removes this automatic assignment to the
COMMON section and directly puts it into .bss. As a result, if more
than one buffer is defined in one file, then it will be removed with --gc-sections
.. not sure if Arduino IDE uses -fno-common... if yes, then the attribute is
redundant.

Notes
This is one of the most critical parts of u8glib. It must be fast, but still reliable.
Based on the intersection program (see tools folder), there is minimized version of
the condition for the intersaction test:
minimized version
---1----0 1 b1 <= a2 && b1 > b2
-----1--0 1 b2 >= a1 && b1 > b2
---1-1--- 1 b1 <= a2 && b2 >= a1
It includes the assumption, that a1 <= a2 is always true (correct, because
a1, a2 are the page dimensions.
The direct implementation of the above result is done in:
uint8_t u8g_is_intersection_boolean(u8g_uint_t a0, u8g_uint_t a1, u8g_uint_t v0, u8g_uint_t v1)
However, this is slower than a decision tree version:
static uint8_t u8g_is_intersection_decision_tree(u8g_uint_t a0, u8g_uint_t a1, u8g_uint_t v0, u8g_uint_t v1)
Also suprising is, that the macro implementation is slower than the inlined version.
The decision tree is based on the expansion of the truth table.

Delay by the provided number of milliseconds.
Thus, a 16 bit value will allow a delay of 0..65 seconds
Makes use of the _delay_loop_2
_delay_loop_2 will do a delay of n * 4 prozessor cycles.
with f = F_CPU cycles per second,
n = f / (1000 * 4 )
with f = 16000000 the result is 4000
with f = 1000000 the result is 250

- movev 1
- subwi 2x2
- bne i 2
==> 7 cycles

Special pin usage:
U8G_PI_I2C_OPTION additional options
U8G_PI_A0_STATE used to store the last value of the command/data register selection
U8G_PI_SET_A0 1: Signal request to update I2C device with new A0_STATE, 0: Do nothing, A0_STATE matches I2C device
U8G_PI_SCL clock line (NOT USED)
U8G_PI_SDA data line (NOT USED)
U8G_PI_RESET reset line (currently disabled, see below)
Protocol:
SLA, Cmd/Data Selection, Arguments
The command/data register is selected by a special instruction byte, which is sent after SLA
The continue bit is always 0 so that a (re)start is equired for the change from cmd to/data mode
