This converts the current string tracking code to using strbuf.
The indent code and tracking for the main + header strings is moved
over.
Now we know the string lengths this also optimises the concatentation.

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.
v1.1: improve indenting
v1.2: fix includes + use memcpy

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.

When changing the from a one-by-one upload to an array upload the test for the
array pointer to the uniform IDs was replaced by testing the uniform array ID
against -1. However, this is not enough, because when the context is allocated
all is cleared to zero, and apparently the structure is re-used in different
invocations of shader programs. Here, one shader might have been removed but
the const field was still allocated resulting in a sigsegv. This happens e.g.
by running
dEQP-GLES31.functional.primitive_bounding_box.wide_points.
global_state.vertex_tessellation_geometry_fragment.fbo_bbox_larger
global_state.vertex_tessellation_geometry_fragment.fbo_bbox_smaller
tessellation_set_per_draw.vertex_tessellation_fragment.default_framebuffer_bbox_equal
tessellation_set_per_draw.vertex_tessellation_fragment.default_framebuffer_bbox_larger
resulting in

The signal is caused by a READ memory access.
