rhg: add RootCommand using hg-core FindRoot operation to prepare `hg root`
The println macro is not used to avoid string usage.
Dealing only with bytes allows us to be compatible with any encoding
and not just UTF8.
Later on, format macro will be made to have more readable code.

archival: abort if compression method is unavailable
`tarfile.CompressionError` is documented to be the "exception for unavailable
compression methods".
Also, make tests conditional on whether the lzma module is available or not.

demandimport: ignore `lzma` module for demandimport
This makes importing the module fail if the `_lzma` module is not present.
This makes e.g. tarfile correctly recognize if LZMA support is not present. It
changes the exception
File "/usr/lib/python3.6/tarfile.py", line 1694, in xzopen
fileobj = lzma.LZMAFile(fileobj or name, mode, preset=preset)
AttributeError: module 'lzma' has no attribute 'LZMAFile'
to the more correct exception
File "/usr/lib/python3.6/tarfile.py", line 1692, in xzopen
raise CompressionError("lzma module is not available")
tarfile.CompressionError: lzma module is not available
Also, it prevents that the error "abort: No module named '_lzma'!" is shown when
a development warning is to be shown. The reason why that happened is that for
showing the warning, we get information about the stack frames from the inspect
module, which accesses the `__file__` attribute of all modules in `sys.modules`
to build some cache, causing all modules (including `lzma`) to be imported.
