This commit modifies the ClientHello writing routine ssl_write_client_hello
in ssl_cli.c to switch between
(a) listing all runtime configured ciphersuites
(in case MBEDTLS_SSL_SINGLE_CIPHERSUITE is not defined)
(b) listing just the single hardcoded ciphersuite
(in case MBEDTLS_SSL_SINGLE_CIPHERSUITE is defined)
The approach taken is to introduce a pair of helper macros
MBEDTLS_SSL_BEGIN_FOR_EACH_CIPHERSUITE( ssl, ver, info )
MBEDTLS_SSL_END_FOR_EACH_CIPHERSUITE
which when delimiting a block of code lead to that block of
code being run once for each ciphersuite that's enabled in the
context `ssl` and version `ver`, referenced through the (fresh)
`info` variable. Internally, this is implemented either through
a plain `for` loop traversing the runtime configured ciphersuite
list (if MBEDTLS_SSL_SINGLE_CIPHERSUITE is disabled) or by just
hardcoding `info` to the single enabled ciphersuite (if
MBEDTLS_SSL_SINGLE_CIPHERSUITE is enabled).
These helper macros will prove useful whereever previous code
traversed the runtime configured ciphersuite list, but adaptations
of those occasions outside ClientHello writing are left for later
commits.
