PR14396: Add pretty-printing support for UTF
* dwarf_wrappers.h: Define DW_ATE_UTF if elfutils < 0.155.
* tapsets.cxx (dwarf_pretty_print::recurse_base): Print UTF with %#c
too. This will generally only work with the ASCII subset for now...
(dwarf_pretty_print::print_chars): Match strings by char/UTF encoding
types, rather than by type name, and use the byte_size to select the
correct string dereferencing function.
* testsuite/systemtap.base/utf_pretty.*: Test it!

PR14396: Add UTF-16/32 conversion functions
* runtime/stp_string.c (_stp_convert_utf32): New, write the given
UTF-32 code point as UTF-8 in the given buffer.
* tapset/linux/conversions.stp (kernel_string_utf32): New, read and
convert a UTF-32 string from kernel memory.
(kernel_string_utf16): Same for UTF-16, handling surrogate pairs.
(kernel_string2_utf32, kernel_string2_utf16): Same w/ custom error.
* tapset/linux/uconversions.stp: All of the above for user memory.
* testsuite/buildok/conversions*.stp: Add build tests.
* testsuite/systemtap.base/utf_*: New runtime tests.

loc2c-runtime.h: Add uread() and uwrite()
These are the userspace equivalents to kread() and kwrite().
For the (unused) STAPCONF_PROBE_KERNEL case, just define them as direct
equivalents. Also add in missing kderef and store_kderef the same way.
For the architecture-implemented case, they are nearly identical to
kread and kwrite, just s/kderef/uderef/. So to avoid duplication, I've
added in a layer of macro indirection to pass in the appropriate deref
function. (Nevermind that the [ku]derefs are often identical -- oh,
what a tangled web we weave...)
