Statically link unixodbc and update configurations

[lovasoa]

Statically link unixODBC and configure rpath to simplify distribution and enable placing ODBC drivers in a sqlpage/ subdirectory.

This change embeds the unixODBC driver manager directly into the SQLPage binary, removing the need for separate installation on target systems. The updated rpath allows database-specific ODBC drivers to be placed alongside the SQLPage executable in a sqlpage/ directory, streamlining self-contained application packaging.

I refactored the build process to statically link unixODBC from source, enhancing portability and reducing runtime dependencies. This involved modifying the Dockerfile to build unixODBC and updating Cargo.toml to conditionally enable static linking for odbc-sys on Unix-like systems. Additionally, I configured RPATHs in .cargo/config.toml for better dependency discovery.

• I implemented a custom build of unixODBC (version 2.3.12) from source within the Dockerfile. This build is configured for static linking (--disable-shared --enable-static) and installed to /opt/unixodbc.
  • I removed unixodbc-dev and libltdl-dev from apt-get install as they are no longer needed, and added make, autoconf, automake, libtool, curl, and ca-certificates as build dependencies.
  • I updated ODBC_LIBDIR to point to /opt/unixodbc/lib and removed the PKG_CONFIG_ALL_STATIC=1 environment variable.
• In Cargo.toml, I refactored the odbc-sys dependency to use target-specific configurations.
  • I moved odbc-sys = { version = "0.27", features = ["static"] } into a [target.'cfg(all(unix, not(target_os = "macos")))'.dependencies] section to enable static linking only for Linux/Unix targets.
  • I added odbc-sys = { version = "0.27" } to a [target.'cfg(any(target_os = "windows", target_os = "macos"))'.dependencies] section for dynamic linking on Windows and macOS.
• In .cargo/config.toml, I added rustflags for specific Linux targets (x86_64-unknown-linux-gnu, aarch64-unknown-linux-gnu, armv7-unknown-linux-gnueabihf).
  • These flags set the runtime library search path (-Wl,-rpath=$ORIGIN/sqlpage:$ORIGIN/lib) to ensure the application can locate its shared libraries at runtime.
