Revert of Create a single command buffer for GrInOrderDrawBuffer (patchset #14 id:1050001 of https://codereview.chromium.org/628453002/)

Reason for revert:
New test failing on Android: http://build.chromium.org/p/client.skia.android/builders/Test-Android-Nexus7-Tegra3-Arm7-Release/builds/89/steps/dm/logs/stdio

Original issue's description:
> Adds a GrTBaseList class that GrInOrderDrawBuffer uses to allocate
> all its commands interleaved in contiguous memory. GrTBaseList also
> supports extra data associated with objects, so we can store arrays
> inline without having to call malloc().

Revert of No threadsafe statics. (patchset #1 id:1 of https://codereview.chromium.org/654663002/)

Reason for revert:
Want to think about how to do this only to skialib and not to tools (gms, tests, etc.)

Original issue's description:
> No threadsafe statics.
>
> Chrome disables these for speed and code size, so we need
> to disable them to make sure our code is safe when used
> this way.

>     int foo() {
>         static int32_t atomic_thing;
>         return sk_atomic_inc(&atomic_thing);
>     }
>
> is not safe in Chrome.  Making the static global is:
>
>     static int32_t atomic_thing;
>     int foo() {
>         return sk_atomic_inc(&atomic_thing);
