* add description of the "-charset" option to the manual page of "ocamldoc"

Escaping strings when printing them in the toplevel has the disadvantage
of mangling unicode text:
```
\# "한글";;
- : string = "\237\149\156\234\184\128"
```
With this commit, strings are not escaped anymore, contrarily to bytes:
```
\# let cosmos = "κόσμος";;
cosmos : string = "κόσμος"
\# Bytes.of_string cosmos;;
- : bytes =
Bytes.of_string "\206\186\207\140\207\131\206\188\206\191\207\130"
```
This new behavior can be disabled dynamically by setting the environment
variable OCAMLTOP_UTF_8 to false
This change is not solely aesthetic: the mangling of unicode string may
contribute to the impression of some OCaml newcomers that Ocaml has no
support for unicode.
* fall back to __secure_getenv when secure_getenv is not available
* use secure_getenv for instrumented runtimes
* documentation: warn against setting the setuid or setgid bits on custom bytecode executables
Since 4.03, OCaml supports coloring its messages to standard output and standard
error, depending on the "-color" argument ({always,never,auto}). This commit
adds support for the environment variable "OCAML_COLOR" (which value can as well
be {always,never,auto}).
The command line argument "-color" takes precedence, "OCAML_COLOR" is only
taken into consideration if no "-color" is provided.
The motivation for this is that the user should have control over coloring
OCaml's output messages. OCamlbuild, a widely used build tool executes OCaml
not under a tty (and OCaml does not colorize errors and warnings), which lead
various packages use `color(always)` in their `_tags` files, which breaks with
other (non-interactive) programs (i.e. editor helpers).
Further discussion was done at https://github.com/ocaml/ocamlbuild/issues/87 and
https://github.com/ocaml/ocaml/pull/1098.
In a format following that of Gc.print_stat. I chose to print only the "quick_stat"
values rather than call gc_ctrl.c::heap_stats because it's lighter, and the extra
information is typically not very useful at program exit.
Also adds documentation for the 0x400 flag (in man and Gc module)
This replaces the previous undocumented 0x400 that only displayed the
total (minwords + majwords - prowords) and with a different format,
since keeping both wouldn't provide more information.
