6ad4f65780 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" \

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

mv cert9?.crt tests/data_files/dir4

2744df4f7a 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.

b76e43651e 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.

5ca3640fa7 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

59efb6a1b9 Fix potential buffer overflow in mpi_read_string() 
Found by Guido Vranken.

Two possible integer overflows (during << 2 or addition in BITS_TO_LIMB())
could result in far too few memory to be allocated, then overflowing the
buffer in the subsequent for loop.

Both integer overflows happen when slen is close to or greater than
SIZE_T_MAX >> 2 (ie 2^30 on a 32 bit system).

Note: one could also avoid those overflows by changing BITS_TO_LIMB(s << 2) to
CHARS_TO_LIMB(s >> 1) but the solution implemented looks more robust with
respect to future code changes.
