The configuration option --with-sha1 is no longer required for the
MESA_SHADER_READ_PATH, MESA_SHADER_DUMP_PATH environment variables
to take effect.
1- removed the "--with-sha1" sentence from docs/shading.html
2- added an extra note: that the corresponding dumped and replacement
shaders must have the same filenames for the feature to take effect.

For the gallium state tracker a tgsi binary may have been evicted
from the cache to make space. In this case we would take the
fallback path and recompile/link the shader.
On i965 there are a number of reasons we can get to the program
upload stage and have neither IR nor a valid cached binary.
For example the binary may have been evicted from the cache or
we need a variant that wasn't previously cached.
This environment variable enables us to force the fallback path that
would be taken in these cases and makes it easier to debug these
otherwise hard to reproduce scenarios.

This is confusing because is only applys to GL_ARB_vertex/fragment_program,
and because of that its also not very useful.
If someone requires this for debugging they can just make an ad-hoc
code change.

Most of them already redirected to https anyway, so we might as well
avoid the redirection and the security implications by linking directly
to the right protocol.

The doc wasn't update since we moved the glsl compiler to src/compiler/glsl.
I also updated the description of the standalone compiler.
v2:
- Mention that just-log argument removes headers/separators.
- Mention that version argument is mandatory.
Since version argument is mandatory, add --version to the command line
example.

Patch modifies existing shader source and replace functionality to work
with environment variables rather than enable dumping on compile time.
Also instead of _mesa_str_checksum, _mesa_sha1_compute is used to avoid
collisions.
Functionality is controlled via two environment variables:
MESA_SHADER_DUMP_PATH - path where shader sources are dumped
MESA_SHADER_READ_PATH - path where replacement shaders are read
v2: cleanups, add strerror if fopen fails, put all functionality
inside HAVE_SHA1 since sha1 is required
