Add PIE and RELRO to binaries

MODULE_LIBS is now part of LIBDOVECOT. No need to explicitly link it everywhere.

Makefile: Link with SSL_LIBS whenever linking libssl_iostream.la

lib-index: Removed the old "mailbox list" type index, which is no longer used. It was rather overdesigned and fragile.

Added "script" service that can be used to easily execute programs via UNIX socket. --HG-- branch : HEAD

Renamed "script" binary to "script-login". --HG-- branch : HEAD

Removed imap-utf7 binary. doveadm mailbox convert replaced it. --HG-- branch : HEAD

Added support for tcpwrappers and potentially other login access checks. --HG-- branch : HEAD

script: Added enough features to get rawlog working again. Also added -d parameter to drop privileges before executing script. --HG-- branch : HEAD

imap, pop3: Added back ability to run post-login scripts. --HG-- branch : HEAD

Makefiles: Separated LIBDOVECOT and LIBDOVECOT_DEPS. --HG-- branch : HEAD

util/*view binaries are now accessed via "doveadm dump". listview binary stays for now, since mailbox list indexes won't work anyway and they might get a complete redesign. --HG-- branch : HEAD

authtest binary is now accessed via "doveadm auth" and "doveadm user". --HG-- branch : HEAD

dovecotpw binary is now accessed via "doveadm pw". --HG-- branch : HEAD

Moved doveadm to a separate directory and made it a bit more easily extensible. --HG-- branch : HEAD

Added authtest utility for doing passdb and userdb lookups. --HG-- branch : HEAD

Added mailboxlogview utility for viewing mailbox logs. --HG-- branch : HEAD

imap_utf7: Renamed to imap-utf7. Also fixed usage error string to print LF. --HG-- branch : HEAD

Some binaries were missing list of library dependencies. --HG-- branch : HEAD

Added configure --without-shared-libs to link built binaries against static libraries. The libraries are still built and installed, so this is mainly useful for making life easier for developers. --HG-- branch : HEAD

Added lib-master and mail-storage-service code that makes it easier to build new Dovecot binaries. Currently only the standalone applications (e.g. deliver) uses this. --HG-- branch : HEAD

Link -liconv to libdovecot.so if necessary. --HG-- branch : HEAD

lib-index belongs to libdovecot-storage, not to libdovecot. --HG-- branch : HEAD

Build libdovecot.so and libdovecot-storage.so. Based on patch by Stephan Bosch. --HG-- branch : HEAD

Added imap_utf7 tool for mUTF-7 <-> UTF-8 conversion. --HG-- branch : HEAD

Rewrote thread indexing code. It's a lot simpler and takes less disk space. We no longer try to keep a hash table and the entire thread tree stored on disk. Instead we keep a simple Message-ID string (actually just "uid, ref#" pointer) -> unique index number mapping on disk, read it to memory and use it to build the thread tree. After the initial build the thread tree is still updated incrementally. --HG-- branch : HEAD

Compiling fix. --HG-- branch : HEAD

Added a new maildirlock utility for write-locking Dovecot MMaildir. --HG-- branch : HEAD

If we need -lcrypto for randomness, put it to $LIBS instead of $RAND_LIBS since it needs to be linked to all binaries anyway. --HG-- branch : HEAD

idxview rewrite. It now uses lib-index functions to read the files. --HG-- branch : HEAD

Added listview utility to show dovecot.list.index.uidmap's contents. --HG-- branch : HEAD

Added idxview and logview to dump index/cache/log file contents. --HG-- branch : HEAD

Added OTP and S/KEY authentication mechanisms. Patch by Andrey Panin. --HG-- branch : HEAD

Added gdbhelper binary. --HG-- branch : HEAD

Upgrades to autoconf 2.5 and automake >1.4. --HG-- branch : HEAD

RAND_LIBS and MODULE_LIBS are needed for dovecotpw. --HG-- branch : HEAD

Added auth/libpassword.a which util/dovecotpw can use rather than using object files directly. --HG-- branch : HEAD

dovecotpw_INCLUDES didn't actually work. Don't even try, src/auth/ must be compiled before we get here. --HG-- branch : HEAD

Added dovecotpw utility. Patch by Joshua Goodall --HG-- branch : HEAD

Keep rawlog still in libexec/dovecot/ directory. --HG-- branch : HEAD

Separated rawlog into it's own binary. --HG-- branch : HEAD
