Auto merge of #25777 - shepmaster:cstring-return-to-c, r=alexcrichton
As far as I was able to determine, it's currently *impossible* to allocate a C NUL-terminated string in Rust and then return it to C (transferring ownership), without leaking memory. There is support for passing the string to C (borrowing).
To complicate matters, it's not possible for the C code to just call `free` on the allocated string, due to the different allocators in use.
`CString` has no way to recreate itself from a pointer. This commit adds one. This is complicated a bit because Rust `Vec`s want the pointer, size, and capacity.
To deal with that, another method to shrink and "leak" the `CString` to a `char *` is also provided.
We can then use `strlen` to determine the length of the string, which must match the capacity.

Auto merge of #26039 - SimonSapin:case-mapping, r=alexcrichton
* Add “complex” mappings to `char::to_lowercase` and `char::to_uppercase`, making them yield sometimes more than on `char`: #25800. `str::to_lowercase` and `str::to_uppercase` are affected as well.
* Add `char::to_titlecase`, since it’s the same algorithm (just different data). However this does **not** add `str::to_titlecase`, as that would require UAX#29 Unicode Text Segmentation which we decided not to include in of `std`: https://github.com/rust-lang/rfcs/pull/1054 I made `char::to_titlecase` immediately `#[stable]`, since it’s so similar to `char::to_uppercase` that’s already stable. Let me know if it should be `#[unstable]` for a while.
* Add a special case for upper-case Sigma in word-final position in `str::to_lowercase`: #26035. This is the only language-independent conditional mapping currently in `SpecialCasing.txt`.
* Stabilize `str::to_lowercase` and `str::to_uppercase`. The `&self -> String` on `str` signature seems straightforward enough, and the only relevant issue I’ve found is #24536 about naming. But `char` already has stable methods with the same name, and deprecating them for a rename doesn’t seem worth it.

Auto merge of #25995 - alexcrichton:msvc-md, r=brson
On MSVC there are two ways that the CRT can be linked, either statically or
dynamically. Each object file produced by the compiler is compiled against
msvcrt (a dll) or libcmt (a static library). When the linker is dealing with
more than one object file, it requires that all object files link to the same
CRT, or else the linker will spit out some errors.
For now, compile code with `-MD` as it seems to appear more often in C libraries
so we'll stick with the same trend.

Rollup merge of #26073 - chuckSMASH:trpl-5-4-comments, r=steveklabnik
For a user following the path of reading Chapter 5: Syntax & Symantics
prior to Chapter 4: Learn Rust, this will be the first time they have
encountered executable tests inside documentation comments.
The test will fail because the `add_one` function is not defined in
the context of the doctest. This might not be the optimal place to
introduce and explain the `/// #` notation but I think it is important
that this snippet pass as a test when `rustdoc --test` is run against
it.
Rollup merge of #25909 - frankamp:patch-1, r=steveklabnik
The doc indicates that you can replace 'before' with 'after' showing the use of try!. The two examples should be equivalent, but they are not.
In the File::create we were inducing a panic before in case of error, not propagating. It is important for newbies (like myself) to understand that try! propagates failures, while unwrap can induce a panic.
The other alternative is to make the 'before' File::create also manually handle Err like the other calls. Either way it would be consistent.
Rollup merge of #25898 - azerupi:patch-3, r=steveklabnik
As mentioned in #25893 the copy trait is not very well explained for beginners. There is no clear mention that all primitive types implement the copy trait and there are not a lot of examples.
With this change I try to make it more visible and understandable for new users.
I myself have struggled with this, see [my question on stackoverflow](http://stackoverflow.com/questions/30540419/why-are-booleans-copyable-even-though-the-documentation-doesnt-indicate-that). And I want to make it more transparent for others.
I filed issue #25893 but I thought that I could give it a shot myself to relieve some of the work from the devs :)
If it is not well written or there are some changes to be made before it can be merged, let me know.

With the latter is provided by the `From` conversion trait, the former is now completely redundant. Their code is identical. Let’s deprecate now and plan to remove in the next cycle. (It’s `#[unstable]`.)
