   fix_limit_checks.patch
     Fix limit checks in writing extensions. BUF_MEM_grow allocates 4/3 the size
     requested, so it doesn't overflow the actual allocation.
 
   reorder_extensions.patch
     Move the ECC extensions to the end of the ClientHello to work around a
     server bug. Some servers are intolerant to the last extension being empty.

 Adding new Chromium patches:
 
 In the event you need to add a new Chromium-specific patch, follow this
 procedure:
 
   1) Use the --temp-dir option to download everything to a known directory
      (by default, import_from_android.sh downloads everything into a
      temporary directory that is erased when the script exits, even in
      case of error).

      (cd /tmp/aaa/build && diff -burN android-openssl.orig android-openssl) > patches.chromium/my-new-change.patch
 
   5) Re-run the script:
 
       ./import_from_android.sh
 
 Generally speaking, consider sending your patch directly to the Android
 open-source review servers too. Once submitted there, you can update
 the git commit in openssl-chromium.org and remove your local patch in
 one new CL.
