This is a MFC of all the commits listed below. My original goal of this change was to only merge the move of the tests from tools/regression/bin/ into the new layout (which include tests for sh(1) and other tools as well). However, doing so is tricky due to the ongoing work in sh(1) and, especially, the many changes to its tests since stable/10 was first branched. Merging everything is the simplest way to achieve this goal and, as a bonus point, we get various fixes and miscellaneous improvements into the branch. Per jilles' suggestion, I'm avoiding the merge of a couple of changes (r256850 and r257506) that required depending kernel changes. I'm also avoiding very recent changes that have not had a long enough time to be validated in current. This is "make tinderbox" clean. r256735 sh: Remove one syscall when waiting for a foreground job. r257399 sh: Allow trapping SIGINT/SIGQUIT after ignore because of '&'. r257504 sh: Reorder union node to reduce its size on 64-bit platforms. r257920 sh: Add a test case for would-be assignments that are not due to quoting. r257929 sh: Properly quote alias output from command -v. r258489 sh: Add tests for the </dev/null implicit in a background command. r258533 sh: Add more tests for the </dev/null implicit in a background command. r258535 sh: Make <&0 disable the </dev/null implicit in a background command. r258776 sh: Prefer memcpy() to strcpy() in most cases. Remove the scopy macro. r259047 sh: Split set -x output into a separate function. r259210 Migrate tools/regression/bin/ tests to the new layout. r259844 sh: Remove an unused variable. r259846 sh: Initialize OPTIND=1 even if it came from the environment. r259874 sh: Simplify code related to PPID variable. r259946 sh: Don't check input for non-whitespace if history is disabled. r260246 sh(1): Discourage use of -e. r260506 Run the sh(1) and test(1) tests as unprivileged. r260586 Mark the bin/pax tests as requiring perl. r260634 Use TAP_TESTS_PERL to register the legacy_test in bin/pax. r260635 Replace hand-crafted Kyuafiles with automatic generation. r260654 sh: Remove SIGWINCH handler and just check for resize before every read. r261121 sh: Add test for nested alias. r261125 sh: Solve the alias recursion problem in a less hackish way. r261141 sh: Do not depend on parse/execute split in new alias test. r261160 sh: Add tests for alias names after another alias. r261192 sh: Allow aliases to force alias substitution on the following word. r262533 sh: Make expari() static. r262565 sh: Do not corrupt internal representation if LINENO inner expansion fails. r262697 sh: Simplify expari().
