  doc: Add include path for sys/usdt.h

When dtrace constructs a USDT header, it includes the header sys/usdt.h.

Add a note to our documentation that /usr/lib64/dtrace/include needs to
be on the include path for this header to be found.

While we are at it, break long lines of text up for better readability
of the Markdown file and simpler diffs in the future.

  Log Message:
  -----------
  Fix printf formatting with non-monetary grouping chars

Non-monetary grouping characters are used to separate groups of digits
in numbers that are not monetary values.  DTrace used to document
support for printf formatting, using a single quote, for such grouping.
Currently, support is largely implemented, but simply not working.

Add a setlocale() call to pick LC_NUMERIC up from environment variables.

  Log Message:
  -----------
  Guard against inserting the same provider twice

Add a safety net to dt_provider_create(), to check if a specified
provider has already been inserted.

This also requires a corresponding change in dt_provider_lookup(), so
that it will work even if no providers have yet been inserted.

  Log Message:
  -----------
  test: correct file permissions

Various tests had a #!-invocation while still being expected to be used
as scripts fed to dtrace.  Removed the #!-lines and marked the files
non-executable.

Various tests that were meant to be invoked as standaline scripts had an
absoolute path to dtrace in the #!-invocation which was not recognized.
runtest.sh expects standalone D scripts to use '#!dtrace' so that the
correct path to the dtrace executable being tested can be inserted.
Corrected the tests, and ensured they are executable.
