[Qemu-trivial] [PATCH] Correct and standardize head er guards in all hea


From: Alexandre Raymond
Subject: [Qemu-trivial] [PATCH] Correct and standardize head er guards in all header files
Date: Sat, 4 Jun 2011 23:57:00 -0400

As per ISO/IEC 9899, Section 7.1.3 on reserved identifiers,
identifiers starting with an underscore are reserved.

Therefore:
1) Rename all incorrect header guards

While I'm at it:
2) Standardize header guards to "#ifndef SOMETHING_H"
3) Repeat the header guard identifier after the closing "#endif"
