Subject: [PATCH] tls_cache: fix implicit conversion err on i386/i686
Previously on arch's where `apr_ssize_t` is an `int` (e.g. i386) the
`tls_cache_get()` function produced an implicit conversion error of the
form:
```
error: implicit conversion changes signedness: 'unsigned int' to 'apr_ssize_t' (aka 'int')
```
This commit resolves this error by:
1. Checking the two casts performed by this function are within the
range of the types being cast to.
2. Making the cast to `apr_ssize_t` explicit.
