apparmor parser fails with ptrace rules and CRLF line endings

[Steve Beattie]

The parser should not fail when ptrace rules and CRLF line endings are used together:

$ file ok_dos_line_endings.sd
ok_dos_line_endings.sd: ASCII text, with CRLF line terminators
$ cat -n ok_dos_line_endings.sd
     1 #
     2 #=Description ptrace peer w/perms and misc modifiers rules w/DOS line endings
     3 #=EXRESULT PASS
     4 #
     5
     6 /usr/bin/foo {
     7 ptrace peer=/usr/bin/top,
     8 # a comment
     9 deny ptrace read peer=/bin/sh,
    10 allow ptrace write peer=/bin/true,
    11 audit ptrace trace peer=/bin/false,
    12 audit deny ptrace readby peer=/sbin/init,
    13 audit allow ptrace tracedby peer=/usr/bin/gdb,
    14 deny ptrace (readby, tracedby) peer=/usr/bin/valgrind,
    15
    16 }
$ ../../../apparmor_parser -qQ ok_dos_line_endings.sd
AppArmor parser error for ok_dos_line_endings.sd in ok_dos_line_endings.sd at line 8: syntax error, unexpected TOK_ID, expecting TOK_CONDID or TOK_END_OF_RULE

Note that the parser succeeds compiling the same profile with unix line endings .
