remove useless spin lock in lib/ast
This spin lock incorrectly implied to the reader that this code was thread safe.
IMHO there are two primary issues with this spin lock and one secondary issue:
1. The intention of the spin lock is clearly to provide mutual exclusion
within fmtbuf(). However this function returns a pointer to a static
(thread-global) buffer. Excluding two threads from being in this function
concurrently does not help if both exit the function with pointers into the
same memory.
2. The spin lock uses no atomics or volatile. As a result, accesses to the
lock can be freely rearranged or coalesced, with no regard to thread
interleaving. This can result in one thread never seeing another thread's
update (unlock) to the lock. Even worse, my local compiler simply
recognizes what is happening and omits the lock operations entirely.
3. (secondary) If this lock worked as intended, it would spin writing to the
lock variable. This would cause fairly pessimistic cache line bouncing as
all waiting processors try to keep the line containing the lock in
exclusive state in their local cache. A more performant way to achieve
this is to spin waiting to see the lock value change *without* modifying
the lock yourself. This allows multiple waiting processors to have the line
in shared state, and minimizes cache coherence traffic.

fix edge attribute order confusion
Certain edge attributes are constructed in advance of their being seen in the
input because Graphviz knows it may need default values for them. Later, if seen
in the input, the values of these attributes are updated.
This all works fine unless the order in which these initially-defaulted edge
attributes appear in the input does not match the order in which the default
versions are constructed by Graphviz internally. In this case, the order in
which the attributes are seen in the input is used to construct a dictionary of
them, but the original copies are used to index into attribute values.
In the particular test case added in this commit,
digraph {
{ rank=same; n1; n2 }
n2 -> n1 [ headport=s, arrowhead=normal ]
}
arrowhead was constructed with symbol ID 0 and headport was constructed with
symbol ID 1. But then the later parsing of these attributes resulted in a
dictionary where the headport value was in ID 0 and the arrowhead value was in
ID 1. Indexing into this dictionary with the initially constructed E_arrowhead
resulted in incorrectly returning the value "s". This caused a spurious error
'Arrow type "s" unknown' as well as incorrect graph output.
Fixes #1444. Note that this may just be one of several issues resulting from
using these initially constructed E_* symbols.

fix: take a copy of font name when caching fonts in Pango plugin
The Pango plugin caches the last used font to save an expensive reconstruction
process each time it runs. To determine whether the cached font is eligible for
reuse, the name and size of the requested font are checked against the cache
entry. However the name of the cached font was only stored as a pointer to the
original name. The cached entry could outlive the original font, which could be
freed before a next call into the plugin. As a result, the plugin would perform
a strcmp using a stale freed pointer.
To address this we simply take a copy of the font name's string data instead of
just a pointer to it. There is no need to copy any of the other cached fields as
they are only accessed if the font name check finds the entry to be valid.

Port rtest.sh ksh code to Python in rtest.py

The reason this is a separate commit from the previoust commit, which
contains the renaming of the file, is to trick git to show the changes
as a one-file diff regardless of the similarity index, rather than one
deleted and one added file. This makes it easier to compare the ksh
code to the Python code.

compiler annotations to explain calling convention of agerr and friends
This change teaches suitably enlightened compilers (Clang and GCC) more about
how these functions are intended to be called. When told to detect misuse of
format strings (`-Wformat`), they can now detect incorrect calls like that fixed

remove unnecessary temporary buffer to construct error message
The motivation for this change is to avoid passing a variable to agerr which
triggers so -Wformat-security errors after some upcoming changes. However, it's
nice to be able to just simplify this code anyway.
