Newest versions of gcc+glibc are able to detect cases where code implicitly casts away const by assigning the result of strchr() or a similar function applied to a "const char *" value to a target variable that's just "char *". This of course creates a hazard of not getting a compiler warning about scribbling on a string one was not supposed to, so fixing up such cases is good. This patch fixes a dozen or so places where we were doing that. Most are trivial additions of "const" to the target variable, since no actually-hazardous change was occurring. Thanks to Bertrand Drouvot for finding a couple more spots than I had. This commit back-patches relevant portions of8f1791c61and9f7565c6cinto supported branches. However, there are two places in ecpg (in v18 only) where a proper fix is more complicated than seems appropriate for a back-patch. I opted to silence those two warnings by adding casts.

PostgreSQL tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check".
