change JAVACALL_REPORT_ERROR and _CRIT logging. review GPIO logging levels

javacall_logging.h file define how to log messages, in revision 110 I 
add a string message strerror(errno) to any ERROR and CRIT message.
This cause wrong behavior for ERROR/CRIT messages generated not after 
system calls, but functions which does not set errno properly.

revision 110 changes reverted.
redundant printouts from gpio.c have been removed.

VTS101 api/jdk/dio/gpio tests failed IOException while opening pin.

line 551 in the original file.

the delay between /sys/class/gpio/gpioN/direction file creation and its 
permission change may be more than 200 milliseconds, this cause IO 
exception pin opening. to pass the tests the delay has to be increased.
