This commit adds a function in Printtyp for searching elements of
the printing environment without reading cmis.
This function is used to ensure that the printing of types does not
trigger unrelated errors by trying to access cmis on the file system.

In presence of -annot, the type printer can be requested to print the
inner path of inline records (i.e "t.A"). Before this commit, the
printing of these paths could trigger a lookup to a module with a
invalid name "t".
If this lookup fails this is fine.
However, if there is a cmi file in the environment sharing the name "t",
the lookup can partially succeed (since cmi are not required to start
with a capital letter) until we compare the module name stored in the
cmi with the requested module name.
Obviously, the valid module name "T" of the cmi cannot match the invalid
module name "t" that was requested, and the cmi reader raises a wrong
module file name error.
This commit avoids this whole process by detecting in the type printer
when we are printing an inlined record type constructor.
The separability signature of a type declaration is not inferred in
a principal way, it depends on the order in which GADT equations are
processed. In non-principal cases, we may have two parameters that are
related by an equality, with one of them being given mode Ind and the
other Sep. Either choice of which to make Sep is sound, but (Ind, Ind)
would be unsound.
We change the implementation to ensure that equations are processed in
an order such that the lefmost parameters are the most constained: if
equations imply that ('a = 'b), with the parameter 'a coming before 'b
in the type declaration, and they must be separable, then 'a gets the
mode Sep and 'b gets the mode Ind. This corresponds intuitively to
remembering that 'b is equal to a previous parameter, instead of
remembering than 'a is equal to a not-seen-yet parameter.
Because this changes the separability of standard library types, and
those separabilities are stored in the .cmi files, this commit changes
the .cmi files in the standard libraries in way that appear to require
a bootstrap (it looks like some part of the stdlib is built with
boot/ocamlc and others with ocamlc, and the two should produce/expect
the same .cmi exactly). The bootstrap will come as a separate commit.
* Avoid inclusion of caml/roots.h to fail when CAML_INTERNALS is defined but not CAML_NAME_SPACE
* preserve documentation

Printexc.uncaught_exception_handler ceases to be an option ref and becomes
a ref to the handler function initialized to
Printexc.default_uncaught_exception_handler.
