Description:
------------
>> Bug #36630  	umask is not being restored when each equest is finished. see for details in bug #36630.
  
this bug not fixed successfully, in file.c is bug in 
        if (BG(umask) != -1) {
                BG(umask) = oldumask;
        }
instead 
        if (BG(umask) == -1) {  /* yes == , no != */
                BG(umask) = oldumask;
        }
it fixes, but for clean code i move initializing 
BG(umask) = -1; from basic_globals_ctor to PHP_RINIT_FUNCTION(basic)   (finalizing is in PHP_RSHUTDOWN_FUNCTION(basic))

this bug is only for sapi apache2 handler-module (apache1 has workaround in sapi code). Or may implement same workaround in apache2 handler module.

i try daily snapshot, and last version, all is bad fixed. after fixing all is ok for testing code 
<?=echo sprintf("%04o",umask(0111));?>



Reproduce code:
---------------
<?=echo sprintf("%04o",umask(0111));?>

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

code is same as for bug 36630, as below, simple, but functional, 
<?=echo sprintf("%04o",umask(0111));?>
expected result is (with default umask 070)
0070
0070
0070
and not
0070
0070
0070
0111
0070
0111  - there is used same process
