checksrc: disallow spaces before labels

Out of 415 labels throughout the code base, 86 of those labels were
not at the start of the line. Which means labels always at the start of
the line is the favoured style overall with 329 instances.

Out of the 86 labels not at the start of the line:
* 75 were indented with the same indentation level of the following line
* 8 were indented with exactly one space
* 2 were indented with one fewer indentation level then the following
line
* 1 was indented with the indentation level of the following line minus
three space (probably unintentional)

parsedate: tune the date to epoch conversion

By avoiding an unnecessary error check and the temp use of the tm
struct, the time2epoch conversion function gets a little bit faster.
When repeating test 517, the updated version is perhaps 1% faster (on
one particular build on one particular architecture).

curl_setup_once: Remove ERRNO/SET_ERRNO macros

Prior to this change (SET_)ERRNO mapped to GetLastError/SetLastError
for Win32 and regular errno otherwise.

I reviewed the code and found no justifiable reason for conflating errno
on WIN32 with GetLastError/SetLastError. All Win32 CRTs support errno,
and any Win32 multithreaded CRT supports thread-local errno.
