convert_to_git(): safe_crlf/checksafe becomes int conv_flags

Browse Source 
When calling convert_to_git(), the checksafe parameter defined what
should happen if the EOL conversion (CRLF --> LF --> CRLF) does not
roundtrip cleanly. In addition, it also defined if line endings should
be renormalized (CRLF --> LF) or kept as they are.

checksafe was an safe_crlf enum with these values:
SAFE_CRLF_FALSE:       do nothing in case of EOL roundtrip errors
SAFE_CRLF_FAIL:        die in case of EOL roundtrip errors
SAFE_CRLF_WARN:        print a warning in case of EOL roundtrip errors
SAFE_CRLF_RENORMALIZE: change CRLF to LF
SAFE_CRLF_KEEP_CRLF:   keep all line endings as they are

In some cases the integer value 0 was passed as checksafe parameter
instead of the correct enum value SAFE_CRLF_FALSE. That was no problem
because SAFE_CRLF_FALSE is defined as 0.

FALSE/FAIL/WARN are different from RENORMALIZE and KEEP_CRLF. Therefore,
an enum is not ideal. Let's use a integer bit pattern instead and rename
the parameter to conv_flags to make it more generically usable. This
allows us to extend the bit pattern in a subsequent commit.
