Replace the v2 blacklist approach with a per-command flag system.
Commands must opt in to being available for untrusted connections
via flag_untrusted_safe (0x400), checked in call_command() which
catches all execution paths including nested commands.
Infrastructure changes:
- Add flag_untrusted_safe to CommandMap
- Add untrusted_error exception type for proper error codes
- Enforce trust check in both call_command() overloads
- Add catch blocks in xmlrpc_c, xmlrpc_tinyxml2, and jsonrpc handlers
- Port SCGI trust state management from v2 (thread_local, header parsing)
- Add _U macro variants in command_helpers.h for safe command registration
- Add CMD2_VAR_*_U and CMD2_VAR_*_U_GET variants for variables
- Close pipe fds on fork failure in ExecFile::execute
- Add exception-safe fclose in cmd_file_append via try/catch
- Add overflow guards before K/M/G bit shifts in parse_whole_value
- Fix %u format for int* in sscanf (change to %d)
- Fix typo "atter"→"after" in error message
$1=$(echo "$result" | tr -d '\n')
removes all newlines without inserting spaces
That usually isn’t what we want for shell lists.
It should typically be space-separated output.
Fixes a bug seen with yocto where compiler is not a single word
but a string e.g.
ccache aarch64-yoe-linux-musl-clang++ -mcpu=cortex-a72+crc+nocrypto --dyld-prefix=/usr -fstack-protector-strong -O2 -D_FORTIFY_SOURCE=2 -Wformat -Wformat-security -Werror=format-security --sysroot=/mnt/b/yoe/master/build/tmp/work/cortexa72-yoe-linux-musl/libtorrent/0.16.1/recipe-sysroot
It changes it to
ccacheaarch64-yoe-linux-musl-clang++-mcpu=cortex-a72+crc+nocrypto--dyld-prefix=/usr-fstack-protector-strong-O2-D_FORTIFY_SOURCE=2-Wformat-Wformat-security-Werror=format-security--sysroot=/mnt/b/yoe/master/build/tmp/work/cortexa72-yoe-linux-musl/libtorrent/0.16.1/recipe-sysroot
When doing c++17 checks on compiler, resulting in failure
