Implement a real Private Browsing Mode condition by changing the API/ABI;
This solves Tor bug #9701, complying with disk avoidance documented in
https://www.torproject.org/projects/torbrowser/design/#disk-avoidance.
1 The GCM test vectors in this directory were downloaded from the NIST
2 Cryptographic Algorithm Validation Program (CAVP) website
3 (http://csrc.nist.gov/groups/STM/cavp/) on Mar 29, 2013 using the URL
4 http://csrc.nist.gov/groups/STM/cavp/documents/mac/gcmtestvectors.zip.
6 The original test files are about 3 MB each, which are too big to
7 include in the NSS source tree. I observed the following patterns in
8 the test vectors:
9 1. Taglen changes in a cycle of 7: 128, 120, 112, 104, 96, 64, 32.
10 2. Then, AADlen changes in a cycle of 5: 0, 128, 160, 384, 720.
12 To reduce the number of test vectors, I kept Taglen = 128, 96 from
13 each cycle of 7, and kept AADlen = 0, 720, 160 from each two cycles
14 of 10.
