The last line of programs/psa/key_ladder_demo.c is of the following
form:
#endif /* Very long comment ... */
Uncrustify tries to reduce the length:
#endif \
/* Very long comment ... */
and causes a compiler error as there is a continuation line with no
actual code in it. Work around this by linewrapping the comment
in advance.

In 'dh_genprime.c', the following condition can be found inside an 'if' statement:
ret = mbedtls_mpi_write_file( "P = ", &P, 16, fout ) != 0
As the '!=' operator binds closer than the assignment operator ('='), the value assigned to 'ret' will be the boolean result of the comparison (0 or 1) instead of the status code returned by 'mbedtls_mpi_write_file'. This means that the above statement is actually equivalent to:
ret = ( mbedtls_mpi_write_file( "P = ", &P, 16, fout ) != 0 )
What we want instead is for the the status code to be assigned to 'ret'. If the value assigned is non-zero, it will be 'truthy' and the 'if' branch will be taken.
( ret = mbedtls_mpi_write_file( "P = ", &P, 16, fout ) ) != 0
This PR fixes the issue by explicitly specifying the precedence of operations with parentheses.

- By default, build version is printed out in the beginning of
ssl_server2 application.
- ./ssl_server2 build_version=1 only prints build verison and stop

SSL programs use certificates in an exchange, so it's more natural
to have such dependency instead of just certificate parsing.

When building SHA512 without SHA384,
there are some code paths that resulted

Some source files had code to set mbedtls_xxx aliases when
MBEDTLS_PLATFORM_C is not defined. These aliases are defined unconditionally
by mbedtls/platform.h, so these macro definitions were redundant. Remove
them.
This commit used the following code:
```
perl -i -0777 -pe 's~#if !defined\(MBEDTLS_PLATFORM_C\)\n(#define (mbedtls|MBEDTLS)_.*\n|#include <(stdarg|stddef|stdio|stdlib|string|time)\.h>\n)*#endif.*\n~~mg' $(git grep -l -F '#if !defined(MBEDTLS_PLATFORM_C)')
```

We used to include platform.h only when MBEDTLS_PLATFORM_C was enabled, and
to define ad hoc replacements for mbedtls_xxx functions on a case-by-case
basis when MBEDTLS_PLATFORM_C was disabled. The only reason for this
complication was to allow building individual source modules without copying
platform.h. This is not something we support or recommend anymore, so get
rid of the complication: include platform.h unconditionally.
There should be no change in behavior since just including the header should
not change the behavior of a program.
This commit replaces most occurrences of conditional inclusion of
platform.h, using the following code:
```
perl -i -0777 -pe 's!#if.*\n#include "mbedtls/platform.h"\n(#else.*\n(#define (mbedtls|MBEDTLS)_.*\n|#include <(stdarg|stddef|stdio|stdlib|string|time)\.h>\n)*)?#endif.*!#include "mbedtls/platform.h"!mg' $(git grep -l '#include "mbedtls/platform.h"')

After opening a file containing sensitive data, call mbedtls_setbuf() to
disable buffering. This way, we don't expose sensitive data to a memory
disclosure vulnerability in a buffer outside our control.
This commit adds a call to mbedtls_setbuf() after each call to fopen(),
but only in sample programs that were calling mbedtls_platform_zeroize().
Don't bother protecting stdio buffers in programs where application buffers
weren't protected.

GCC 12 emits a warning because it thinks `buffer1` is used after having been
freed. The code is correct C because we're only using the value of
`(uintptr_t)buffer1`, not `buffer1`. However, we aren't using the value for
anything useful: it doesn't really matter if an alloc-free-alloc sequence
returns the same address twice. So don't print that bit of information, and
this way we don't need to save the old address.
Fixes#5974.
