emit_ios handles all the shader types so that it is difficult to
follow what is emitted for which shader type. Start refactoring by
moving the common initialization into a separate function.

There's no point in keeping updating all the constant buffers for every
draw; we only need to update those who has changed since last draw.

This allows us to allocate UBO ids based on the linked result, rather
than the currently bound UBOs. This gives us a per-program stable
result, which means we don't need to keep updating them.

We already track samplers, images and ssbos using bitmasks, so this is a
bit more familiar to the rest of the code.
Also, this is going to enable some other nifty optimizations later on.

We have call-sites where we already know the length of the string,
so calling strlen is entirely needless. So let's introduce a variant
called strbuf_append_buffer that takes an explicit length, and make
strbug_append call that instead.

TGSI_OPCODE_BFI and TGSI_OPCODE_ATOMCAS takes four source arguments,
so we actually need to support up to four members here. Luckily, the
storage passed to this function was large enough, so no actual harm
happened, just a small semantic issue when reading the source code.

This adds a string buffer implementation + unit tests with
the following features:
- growing reallocation on append
- variadic printf-like append function
- indenting
- error state tracking (stop appending on errors)
This will be used in the GLSL shader construction to clean up
the bad string length issues we have now.
The variadic append is based on one Erik Faye-Lund wrote.

When the host GL version is < 4.0 then the GLSL shader language level is set
to a value below 400, but if geometry shaders, tesselation shaders, and the
gpu_shader5 are supported, then we can expect that the GLSL language level
400 is actually supported, so advertice it also on a GL host.
