The render server is a daemon that sits idle waiting for commands. When
requested to create a context, it forks and creates the context in a
subprocess. This isolates contexts from each other, from the server
process, and from the client process.
Because a context process can execute untrusted commands and depends on
GPU drivers, the isolation should improve the security.
There is also a multi-thread mode where each context is executed by a
thread. This mode is used to ease debugging, but maybe someone will
find a use case for it.

With -Dvenus-validation=true, vkr will enable the validation layer by
setting
ctx->validate_level = VKR_CONTEXT_VALIDATE_ON;
ctx->validate_fatal = false;
We would like to set ctx->validate_fatal to true, but even vulkaninfo
has validation errors. We should create a list of VUIDs that are
considered non-fatal before we can set ctx->validate_fatal to true.

- Make stubs inline code so it can be optimized away.
- Add compile with tracing info to configuration status

other tracing tools cold be accomodated
(inspired by Chia-I Wu & Tomeu)

Since vtest_server and the tests make use of private interfaces we must
mirror the autotoosl build that keeps the private interfaces in a static
library so that these functions can be called by the test code. The main
library that get installed then uses this static library and adds the
exported interface.
