adb/base: minor compiler portability improvements

I've been using these changes to compile with Visual Studio.

- GetFileBasename(): __FILE__ uses \ with Visual Studio.

- adb_trace.cpp: Apparently VS needs an ampersand before the function name.

- "expr1 ? : expr2" is a GCC extension.

- <algorithm> contains std::min().

- seekdir can't always be #define'd because some headers have members
  named seekdir.

- adb_utils.cpp: Not really a compiler issue, just a random fix:
  0x7F/DEL is not printable.
