This PR adds a new API function char *texerrors_str(), which is similar to texerrors() but returns a string (of ;-delimited error messages) rather than printing to stderr.
Rationale: returning a string makes it easier for the caller to decide what to do with the error message, and is especially important for calling from higher-level languages where the error message is typically wrapped in a thrown exception. (cc @Suavesito-Olimpiada)
It adds a test script testerrors.sh to check that it is working. I also updated the test scripts so that they use a $utftex environment variable (set by the Makefile) rather than running utftex from the $PATH. On my machine, make check gives:
