Function fts_palloc

util/folder/fts.cpp:1286–1292

* Allow essentially unlimited paths; find, rm, ls should all work on any tree. * Most systems will allow creation of paths much longer than MAXPATHLEN, even * though the kernel won't resolve them. Add the size (not just what's needed) * plus 256 bytes so don't realloc the path 2 bytes at a time. */
