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.

v2: - Include perfetto_min.h only when perf tracing is enabled
- Make stubs inline code so it can be optimized away.
- Add compile with tracing info to configuration status
- Use static for stubs (Chia-I Wu)
- pass trace option as a string and add defines so that
other tracing tools cold be accomodated
(inspired by Chia-I Wu & Tomeu)
- Use macros to wrap the trace calls
v3: - Use __attribute__((cleanup)) to handle trace_begin/trace_end
instead of using macros to wrap the calls (Chia-I Wu)
- remove cpp from language support
v4: - Fix __attribute__ check in meson.build
- replace TRACE_FUNC macro to not take a paramter
- move trace initialization to a seperate function
(all suggestions by Chia-I Wu)
v5: use vsnprintf to avoid buffer overflow (John Bates)

This is currently only used with minigbm, and largely untested
elsewhere. This will also allow us to use flags which are not
available in Mesa GBM.

This patch adds the meson build system as alternative to the
autotools build system.
v2: Thanks to Alexandros for his comments that lead to the following changes:
- Fix logic for platforms so that the ones selected by 'auto' don't
fail if the dependencies are missing, but fail when explicitely
requested
- declare project version differently
- set a minimun meson version
- clean up some braces
- reformat some code
- squesh remaining separate patches
v3: require meson 0.46 (Gurchetan)
v4: set minimum gbm version to 18.0.0
v5: - fix gbm version requirement (Gurchetan)
- don't duplicate glx files (Gurchetan)
