fix buffer under-read in fdp

When using fdp to process a graph, it would try to canonicalize all node names,
regardless of whether they were hosted in refstr_ts or not. The problem with
this is that the canonicalization logic assumes the character pointer passed
into it is within a refstr_t and that therefore it can do pointer subtraction to
get a pointer to the refstr_t itself. This was not true for internally
constructed node names like "%4".

We change this to always go through the refstr logic in agstrdup() when
canonicalizing names. This ensures that the pointer we pass into the
canonicalization logic *is* within a refstr_t. This is based on canon() in
lib/cgraph/output.c. Fixes #236, #1290, #1865.

Matthew Fernandez [Sat, 31 Oct 2020 16:28:24 +0000 (09:28 -0700)]
fix: fclose(NULL) in the VRML plugin when current directory is not writable

The VRML plugin writes PNG files of each node in the graph alongside the VRML
output that then references these files. If you give no output location (do not
pass `-o` to dot), the VRML output is written to stdout and the node PNG files
are written to the current directory. However, the plugin was not checking
whether opening of these PNG files succeeded. As a result, if the current
directory was not writable, it would end up calling fclose() with a NULL
pointer.

This change makes the plugin report the failure to open PNG files and cause dot
to eventually exit with non-zero. Note that VRML processing is not stopped, so
the user can still get complete VRML output, albeit missing the associated PNG
files that will be referenced.

The test case included in this commit does not necessarily reproduce the failure
prior to these changes. This is because Glibc allows fclose(NULL). However, this
is beyond the spec and other libcs do not provide these guarantees.

Fixes #793.
