Damien George 96740be357 py/mperrno: Define MP_EWOULDBLOCK as EWOULDBLOCK, not EAGAIN.
Most modern systems have EWOULDBLOCK aliased to EAGAIN, ie they have the
same value.  But some systems use different values for these errnos and if
a uPy port is using the system errno values (ie not the internal uPy
values) then it's important to be able to distinguish EWOULDBLOCK from
EAGAIN.  Eg if a system call returned EWOULDBLOCK it must be possible to
check for this return value, and this patch makes this now possible.

Damien George a559098fec py/mperrno: Allow mperrno.h to be correctly included before other hdrs.
Before this patch the mperrno.h file could be included and would silently
succeed with incorrect config settings, because mpconfig.h was not yet
included.

Alexander Steffen 299bc62586 all: Unify header guard usage.
The code conventions suggest using header guards, but do not define how
those should look like and instead point to existing files. However, not
all existing files follow the same scheme, sometimes omitting header guards
altogether, sometimes using non-standard names, making it easy to
accidentally pick a "wrong" example.

This commit ensures that all header files of the MicroPython project (that
were not simply copied from somewhere else) follow the same pattern, that
was already present in the majority of files, especially in the py folder.

The rules are as follows.

Naming convention:
* start with the words MICROPY_INCLUDED
* contain the full path to the file
* replace special characters with _

In addition, there are no empty lines before #ifndef, between #ifndef and
one empty line before #endif. #endif is followed by a comment containing
the name of the guard macro.

py/grammar.h cannot use header guards by design, since it has to be
included multiple times in a single C file. Several other files also do not
need header guards as they are only used internally and guaranteed to be
included only once:
* MICROPY_MPHALPORT_H
* mpconfigboard.h
* mpconfigport.h
* mpthreadport.h
* pin_defs_*.h
* qstrdefs*.h

Paul Sokolovsky 5da8de2b66 extmod/modlwip: Fix error codes for duplicate calls to connect().
If socket is already connected, POSIX requires returning EISCONN. If
connection was requested, but not yet complete (for non-blocking
socket), error code is EALREADY.

Damien George 9a92499641 py/objexcept: Don't convert errno to str in constructor, do it in print.
OSError's are now printed like:

    OSError: [Errno 1] EPERM

but only if the string corresponding to the errno is found.

Damien George d45e5f8c35 py: Add mp_errno_to_str() and use it to provide nicer OSError msgs.
If an OSError is raised with an integer argument, and that integer
corresponds to an errno, then the string for the errno is used as the
argument to the exception, instead of the integer.  Only works if
the uerrno module is enabled.
