872948cc72 Support larger integer test arguments: C part
Change the type of signed integer arguments from int32_t to intmax_t.
This allows the C code to work with test function arguments with a range
larger than int32_t. A subsequent commit will change the .datax generator
to support larger types.

b3c2eaf00f Support different types in the parameter store
The test framework stores size_t and int32_t values in the parameter store
by converting them all to int. This is ok in practice, since we assume int
covers int32_t and we don't have test data larger than 2GB. But it's
confusing and error-prone. So make the parameter store a union, which allows
size_t values not to be potentially truncated and makes the code a little
clearer.

5226eb5cd3 Simplify parsing of integers in .datax files
In the .datax parser, since we're calling strtol() anyway, rely on it for
verification. This makes the .datax parser very slightly more
liberal (leading spaces and '+' are now accepted), and changes the
interpretation of numbers with leading zeros to octal.

Before, an argument like :0123: was parsed as decimal, but an argument like
:0123+1: was parsed as a C expression and hence the leading zero marked an
octal representation. Now, a leading zero is always interpreted according to
C syntax, namely indicating octal. There are no nonzero integer constants
with a leading zero in a .data file, so this does not affect existing test
cases.

In the .datax generator, allow negative arguments to be 'int' (before, they
were systematically treated as 'exp' even though they didn't need to be).

In the .datax parser, validate the range of integer constants. They have to
fit in int32_t. In the .datax generator, use 'exp' instead of 'int' for
integer constants that are out of range.

1a24895bfd Simplify string escapes
Treat backslash as a universal escape character: "\n" is a newline,
backslash escapes any non-alphanumeric character.

This affects some test cases that had "\," standing for backslash-comma.
With the new uniform treatment of backslashes, this needs to be "\\,".

89615eefe7 Show values when TEST_EQUAL fails
When TEST_EQUAL fails, show the two numerical values in the test log (only
with host_test). The values are printed in hexa and signed decimal.

The arguments of TEST_EQUAL must now be integers, not pointers or floats.
The current implementation requires them to fit in unsigned long long
Signed values no larger than long long will work too. The implementation
uses unsigned long long rather than uintmax_t to reduce portability
concerns. The snprintf function must support "%llx" and "%lld".

For this purpose, add room for two lines of text to the mbedtls_test_info
structure. This adds 154 bytes of global data.

5a7702e76d Fix some C function documentation in the test framework
The primary goal of this commit is to fix various comments where
`clang -Wdocumentation` identified a discrepancy between the actual
function parameters and the documented parameters. The discrepancies
were due to copypasta, formatting issues or documentation that had

06725c985f Fix intermittent crash in test suites with outcome file enabled
Fix an intermittent crash when running test suites in non-verbose
mode (i.e. with -v off) and with the outcome file enabled. The
array unmet_dependencies was only filled in verbose mode, but was used
in write_outcome_result regardless.

Since unmet_dependencies only ever contains strings that are integers
written out in decimal, store the integer instead. Do this
unconditionally since it doesn't cost any extra memory.

It would be better to record the dependency names, both in the verbose
output and in the outcome file. But the dependency names are not
currently available at runtime.

6542f6c597 Change the use of setjmp/longjmp in parameter failure callback
Change the use of setjmp and longjmp in signalling parameter validation failures
when using the MBEDTLS_CHECK_PARAMS config.h option. This change allows
all calls which might result in a call to the parameter validation failure
handler to always be caught, even without use of the new macros, by placing a
setjmp() in the outer function which calls the test function, which the handler
can jump to.

This has several benefits:
    * it allows us to remove the clang compiler warning (-Wclobbered) caused
      by local auto variables being in the same function as the call to setjmp.
    * removes the need to wrap all function calls in the test functions with the
      TEST_ASSERT() macro. Now all parameter validation function calls should be
      caught.

76135345c8 Fix gcc-7 -Wformat-truncation warning
Function test_snprintf() is called by run_test_snprintf() with constant test
data. It gets inlined and is subjected to snprintf format truncation checks
introduced by -Wformat-truncation in gcc-7. -Wformat-truncation is turned
On by -Wall and other similar options. It results in error with -Werror.

-Wformat-truncation makes tests performed by run_test_snprintf() redundant
on gcc. But they are still relevant for other compilers. This commit prevents
inlining of test_snprintf() to avoid gcc compile time checks.
