2ba6aa6045 Fix memory leak in case allocation of token fails during JSON parsing
On failure of json_alloc_token(), json_parse() can return without
freeing 'str' previously allocated by json_parse_string(). Fix this
adding proper call to os_free().

b22608423b Clean up base64_url_{encode,decode} pointer types
Allow any pointer to be used as source for encoding and use char * as
the return value from encoding and input value for decoding to reduce
number of type casts needed in the callers.

1030dec1fa JSON: Fix escaping of characters that have MSB=1 with signed char
The "\\u%04x" printf string did not really work in the correct way if
char is signed. Fix this by type casting this to unsigned char.

This would have resulted in reading one octet past the end of the buffer
before rejecting the string.

281f480c53 JSON: Fix a memory leak on an error path
If the second json_alloc_token() call failed to allocate memory,
json_parse() missed the first allocation on the error path. Assign the
root pointer earlier for that case to avoid the potential memory leak.
