Manuel Pégourié-Gonnard b030c33e57 Fix bug checking pathlen on first intermediate 
Remove check on the pathLenConstraint value when looking for a parent to the
EE cert, as the constraint is on the number of intermediate certs below the
parent, and that number is always 0 at that point, so the constraint is always
satisfied.

The check was actually off-by-one, which caused valid chains to be rejected
under the following conditions:
- the parent certificate is not a trusted root, and
- it has pathLenConstraint == 0 (max_pathlen == 1 in our representation)

fixes #280

Manuel Pégourié-Gonnard 3cb2074a82 Add test case for root with max_pathlen=0 
This was already working but not tested so far

(Test case from previous commit still failing.)

Test certificates generated with:

programs/pkey/gen_key type=ec ec_curve=secp256r1 filename=cert91.key
programs/pkey/gen_key type=ec ec_curve=secp256r1 filename=cert92.key

programs/x509/cert_write serial=91 output_file=cert91.crt is_ca=1 \
    issuer_key=cert91.key issuer_name="CN=Root 9,O=mbed TLS,C=UK" \
    selfsign=1 max_pathlen=0

    subject_key=cert92.key subject_name="CN=EE 92,O=mbed TLS,C=UK"

mv cert9?.crt tests/data_files/dir4

Manuel Pégourié-Gonnard c28240596a Fix other int casts in bounds checking 
Not a security issue as here we know the buffer is large enough (unless
something else if badly wrong in the code), and the value cast to int is less
than 2^16 (again, unless issues elsewhere).

Still changing to a more correct check as a matter of principle

Jonathan Leroy 00c6b3c35a Fix boolean values according to DER specs 
In BER encoding, any boolean with a non-zero value is considered as
TRUE. However, DER encoding require a value of 255 (0xFF) for TRUE.

This commit makes `mbedtls_asn1_write_bool` function uses `255` instead
of `1` for BOOLEAN values.

With this fix, boolean values are now reconized by OS X keychain (tested
on OS X 10.11).

Fixes #318.

Jonathan Leroy 3dd85ddfdf cert_write : fix "Destination buffer is too small" error 
This commit fixes the `Destination buffer is too small` error returned
by `mbedtls_cert_write` command when the values of `subject_name` or
`issuer_name` parameters exceed 128 characters.

I have increased the size of these varaibles from 128 to 256 characters,
but I don't know if it's the best way to solve this issue...

Fixes #315.

Actually all key exchanges that use a certificate use signatures too, and
there is no key exchange that uses signatures but no cert, so merge those two
flags.
