Follow-up to r7838, remove unecessary import

Catch unicode exception raised during Genshi rendering and give some hints about the location of the original error.

Fixes #7959.

Allow plugins to have options with non-ascii documentation.

Patch from trac-ja, on #7845.

On Windows, when a relative path is used for the SVN's `repository_dir`, the case of the normalized path could change depending on the situation (different CWD?), so we should normalize the case when checking if the repository_dir has changed.

Closes #7844.

Use `log.error` instead of `log.exception` for notification errors, as we don't really need a backtrace here, and make this error reporting unicode safe.

This lead to fix most other places where we show exception in the log.
I also replaced the `log.error(..., exc_info=True)` with calls to `exception_to_unicode`, as the former will hide the unicode strings if any, showing "<unprintable Exception object>" instead.

Closes #7935.

Convert !SubversionException to !TracError after failing to open the repository, so that it can properly be transformed into a warning instead of showing up as an internal error.

Fixes #8024.

In attachment list page, change title of button from "Attach file" to "Attach another file", for increased clarity, especially when reaching that page after having added the first attachment.

Closes #8016.

Don't split CamelCase wiki names when the page is not found and both `split_page_names` and `ignore_missing_pages` `[wiki]` options are set.

Fixes #8033.

TracMercurial for 0.11: backported r7830 from 0.12 branch (''fix for #7981'')

TracMercurial for 0.12: linkrev takes a rev number instead of a node since hg:9fe97eea5510.

Fixed by using filectx API. Closes #7981.
