encoding: fix trim() to be O(n) instead of O(n^2)
`encoding.trim()` iterated over the possible lengths smaller than the
input and created a slice for each. It then calculated the column
width of the result, which is of course O(n), so the overall algorithm
was O(n). This patch rewrites it to iterate over the unicode
characters, keeping track of the length so far. Also, the old
algorithm started from the end of the string, which made it much worse
when the input is large and the limit is small (such as the typical 72
we pass to it).
You can time it by running something like this:
```
time python3 -c 'from mercurial.utils import stringutil; print(stringutil.ellipsis(b"0123456789" * 1000, 5))'
```
That drops from 4.05 s to 83 ms with this patch (and most of that is
of course startup time).

share-safe: enable by default (BC)
The feature have been around for a year (4 version) and is quite important.
Lets make it enabled by default.

share-safe: add support for static-http repository
We need to read the second requirements file in the static-http case too. Otherwise, static-http would miss most of the requirements and misbehave.

legacy-revlog: fix requirement computation when cloning legacy repo
The oldest format of repository does not have requirements so we need to treat
them differently when cloning such repository.
The previous code had issue whenever we start using a working-copy-only
requirements. The "legacy" format is signaled using an empty requirements list.
If we add working-copy-only requirements to it, this is no longer empty, and
no longer legacy.
The new code fix this, and will get fully tested in a couple of changeset, once the
share-safe become the default.

requirements: do not warn about dropping share-safe, unless explicitly set
If we are just altering the default value, this is "fine". This will get tested

with `share-safe`, we will also write file in the store. So we take the `lock`

tests: use debugrequires instead of grepping the file directly
With `share-safe`, the requirements are stored in multiple files so it seems
better to use the command that retrieve the information wherever it is.
