Implement different accuracy levels for the mailbox format detection
Selecting the accuracy level allows the user to achieve the desired balance between the speed of the folder scan and accuracy of mailbox format detection. The accuracy level can be set either from the configuration file, using the mailbox.accuracy-level statement, or from the environment, using the MU_AUTODETECT_ACCURACY variable. The default accuracy level 1 discerns valid mbox and dotmail mailboxes providing reasonable scan speed. Level 0 (previous default) does not discern them, but provides maximal speed. Level 2 and higher provide better accuracy at the price of speed. * include/mailutils/url.h (MU_AUTODETECT_ACCURACY_AUTO) (MU_AUTODETECT_ACCURACY_FAST) (MU_AUTODETECT_ACCURACY_DEFAULT): New constants. (mu_scheme_autodetect_p): New proto, moved here from util.h (mu_set_autodetect_accuracy) (mu_autodetect_accuracy): New protos. * libmailutils/base/schemeauto.c (mu_set_autodetect_accuracy) mu_autodetect_accuracy): New functions. * libmailutils/cli/stdcapa.c: New configuration statement: mailbox.autodetect-accuracy. * libmailutils/url/create.c (_mu_url_create_internal): Assume the "file" scheme if the MU_URL_PARSE_LOCAL flag is set. * libproto/dotmail/folder.c: Implement format detection. Three accuracy levels: 0, 1, and >1 * libproto/mbox/folder.c (_mbox_is_scheme): Implement default format detection. * libproto/dotmail/tests/Makefile.am: Add new test. * libproto/dotmail/tests/autodetect.at: New test. * libproto/dotmail/tests/dm_detect.c: New file. * libproto/dotmail/tests/testsuite.at: Add new test.
