Merge of r4870, r4871, r4890, r4895: minor fixes.
*) Made sure to initialize the entire ngx_file_t structure.
Found by Coverity.
*) Correct plural form for "path" in the whole source base.
*) Removed conditional compilation from waitpid() error test.
There are reports that call to a signal handler for an exited process
despite waitpid() already called for the process may happen on Linux
as well.
*) Style, parentheses instead of braces in misc/GNUMakefile.
