[PATCH 0/5] Handling for TAP header level

[Shuah Khan]

This patch series is a result discussion with Tim Bird about nested TAP
header handling. Based on the discussion, I am introducing a environment
variable to prevent nested TAP headers. These patches improve the run_tests
output and the output from the script generated by emit_tests.
    
This first patch in this series adds environment variable KSFT_TAP_LEVEL
to avoid printing nested TAP headers for each test. lib.mk run_tests
target prints TAP header before invoking the test program or test script.
Tests need a way to suppress TAP headers if it is already printed out.

This new environment variable adds a way for ksft_print_header()
print TAP header only when KSFT_TAP_LEVEL isn't set.
  
The second patch in this series changes lib.mk run_tests target to set
KSFT_TAP_LEVEL before running tests.

The third patch changes Makefile to export KSFT_TAP_LEVEL and adds
TAP and KSFT_TAP_LEVEL handling to emit_tests target.
 
Forth and fifth patches make changes to size and futex tests to
prevent nested TAP headers to take advantage of the framework
change in the first patch.

  selftests: lib.mk set KSFT_TAP_LEVEL to prevent nested TAP headers
  selftests: Makefile set KSFT_TAP_LEVEL to prevent nested TAP headers
  selftests: size call ksft_print_header() to print TAP header
